id="Camel2.16.0Release-NewandNoteworthy">New and Noteworthy</h2><p>Welcome to
the 2.16.0 release which approx XXX issues resolved (new features, improvements
and bug fixes such as...)</p><p>Noteworthy improvements:</p><ul><li>The route
models (definition classes) preserve property placeholders, which allows round
trip editing, and also prevents showing potential sensitive
information</li><li>Added onPrepareFailure option to <a shape
="rect" href="dead-letter-channel.html">Dead Letter Channel</a> to allow a
custom processor to prepare the Exchange before sending to the dead letter
queue.</li><li><a shape="rect" href="mongodb.html">MongoDB</a> tailable
consumers now allow setting the <code>readPreference</code>
option.</li><li>Using setFaultBody / setFaultHeader behaves similar to setBody
/ setHeader to preserve existing headers/attachments by setting on existing IN
or OUT message.</li><li>Java DSL using choice with end vs endChoice now
validates you use them as intended. Any misconfiguration now throws an
exception explaining the problem.</li><li><a shape="rect"
href="pojo-producing.html">POJO Producing</a> and <a shape="rect"
href="pojo-consuming.html">POJO Consuming</a> lifecycle is now in sync with <a
shape="rect" href="camelcontext.html">CamelContext</a> which ensures it
works as similar to Camel <a shape="rect" href="routes.html">Routes</a>
does. Also the created producer/consumer is stopped
when <a shape="rect" href="camelcontext.html">CamelContext</a> is
stopping to cleanup properly.</li><li><a shape="rect"
href="jms.html">JMS</a> component now allows configuring
concurrentConsumers/maxConcurrentConsumers separately between from(jms) vs
to(jms) using request/reply over JMS</li><li><span><a shape="rect"
class="external-link"
href="https://issues.apache.org/jira/browse/CAMEL-8506";>Added SEARCH</a>
operation to Elasticsearch component</span></li><li><span>The <a
shape="rect" href="properties.html">Properties</a> component (property
placeholder) now supports an encoding option to allow reading the .properties
files using a specific charset such as UTF-8. By default ISO-8859-1 is used
(latin1)</span></li><li><span>Added <code>receviveBufferSize</code> option
to the <a shape="rect" href="ftp.html">FTP</a> component to make download
faster. The size is by default 32kb buffer.</span></li><li><span>The <a
shape="rect" href="aggregator2.html">
Aggregator2</a> EIP now allows an external source using
a <code>AggregateController</code> to control the aggregator, such as for
forcing completing a group or all groups, or query runtime information from the
aggregator. A default controller is provided out of the box if none has been
configured.</span></li><li><span>The <a shape="rect"
href="aggregator2.html">Aggregator2</a> now enlists in JMX using
a <code>ManagedAggregateProcessorMBean</code> which has more information,
and also allows using the aggregate controller to control
it.</span></li><li><span>The <a shape="rect"
href="aggregator2.html">Aggregator2</a> now includes more runtime statistics
which can be accessed from Java and JMX about number of incoming and completed
exchanges, and per different completion
triggers.</span></li><li><span>The <a shape="rect"
href="aggregator2.html">Aggregator2</a> now supports pre-completion mode if the
aggregation strategy implements <code>PreCompletionAwareAg
gregationStrategy</code>. This supports the use-case where an incoming
Exchange are used to determine if the current aggregated group is completed or
not. If completed the group is emitted as-is, and the new incoming Exchange is
used to start a new group from scratch.</span></li><li><span>Added options
to <a shape="rect" href="mail.html">Mail</a> consumer so it can skip or
handle a mail message that cannot be read from the mail server in the batch;
and then move on to read the next message. This ensures the consumer can deal
with mail boxes that has problematic mails that otherwise will cause no mails
to be retrieve by the consumer in the batch.</span></li><li>The runtime route
processors and their corresponding model definition are now linked by their id
using <code>HasId</code>, so its easier to obtain the processor or model
definition from the <code>getProcessor(id)</code> and
<code>getProcessorDefintion(id)</code> api on
CamelContext.</li><li>CamelContext now also
includes a getManagedProcessor API to easily get the mbean client api for the
processor, so you can access the runtime JMX statistics from Java
code. </li><li><span><a shape="rect" href="spring-boot.html">Spring
Boot</a> applications now <a shape="rect" class="external-link"
href="https://issues.apache.org/jira/browse/CAMEL-8532";>block the main thread
of the execution</a></span></li><li><span><a shape="rect"
href="spring-boot.html">Spring Boot</a> automagically <a shape="rect"
class="external-link"
href="https://issues.apache.org/jira/browse/CAMEL-8523";>loads XML routes
definitions</a> from
classpath</span></li><li><span>Added <code>MainListener</code> to make it
easier for Camel Boot / Standalone Camel to implement custom logic to trigger
during the starting and stopping of the
application.</span></li><li><span><span>Camel Jackson now provides <a
shape="rect" class="external-link"
href="https://issues.apache.org/jira/browse/CAMEL-8554";><code>Map</code> to
<code>Object</c
ode> converter</a></span></span></li><li><span>Ability to refer to existing
hazelcast instance by id, using <a shape="rect"
href="hazelcast-component.html">Hazelcast Component</a></span></li><li><a
shape="rect" href="direct.html">Direct</a> and <a shape="rect"
href="direct-vm.html">Direct-VM</a> now supports
the <span>failIfNoConsumers option</span></li><li>Making it easier to add
custom <a shape="rect" href="type-converter.html">Type Converter</a> to
your Camel applications without having to use the META-INF file. In Spring or
Blueprint just add them as <bean>s. See more details at <a
shape="rect" href="type-converter.html">Type Converter</a>
documentation.</li><li>camel-cxf PAYLOAD supports stream cache out of
box.</li><li><p><code>BridgePropertyPlaceholderConfigurer</code> supports to
handle the <span><a shape="rect" href="jasypt.html">jasypt </a>encryption
inside and outside of the camelContext.</span></p></li><li><p>The camel-aws
component now sup
port Amazon DynamoDB version 2<span><br
clear="none"></span></p></li><li><p>The <a shape="rect"
href="wire-tap.html">Wire Tap</a> eip now also emits event notifications when
sending the Exchange to the wire tap destination</p></li><li><a shape="rect"
href="camel-test.html">Camel Test</a> has new option isDumpRouteStats that
dumps all route usage statistics as XML files in target/camel-route-stats
directory, which can be used to inspect "route coverage" reports.</li><li>Now
<a shape="rect" href="netty4.html">Camel Netty</a> component doesn't intercept
consumers with <code>httpMethodRestrict=OPTIONS</code></li><li><span>Now <a
shape="rect" href="netty4-http.html">Netty HTTP</a> resolves OPTIONS prefix
matches earlier</span></li><li>Using <a shape="rect"
href="load-balancer.html">Load Balancer</a> with Java DSL now builds the route
model using the specific model types, which renders a more accurate route
model</li><li>Enhanced the PredicateBuilder to support vargs and list in
the "or" builder method</li><li>Using custom <code>HttpBinding</code>
with <a shape="rect" href="http.html">HTTP</a> and <a shape="rect"
href="http4.html">HTTP4</a> is now easier as they can be instantiated using a
default no-arg constructor</li><li>Added <code>readLock=idempotent</code>
to the <a shape="rect" href="file2.html">File2</a> consumer which allows
to reuse an idempotent repository as read-lock which enables Camel to run
reliable in clustered mode, where each node competes for the same files from a
shared file system. This requires that the idempotent repository supports
clustering such as <a shape="rect"
href="hazelcast-component.html">Hazelcast Component</a> or <a shape="rect"
href="infinispan.html">Infinispan</a> - or using the JDBC for a shared database
table.</li><li><a shape="rect" href="rx.html">Camel RX</a> now ensures that
observe and subscribe are done within an unit of work to ensure on completions
is executed, such as they a
re done when you use regular Camel routes.</li><li>The <a shape="rect"
href="jms.html">JMS</a> component now includes the
underlying <code>javax.jms.Session</code> instance on the Camel message
which allows end users to easier to use client acknowledge mode, in case the
client wants to use the session to call recover or rollback.</li><li>Added
<code>completionEager</code> option to <a shape="rect"
href="idempotent-consumer.html">Idempotent Consumer</a> to whether to complete
the idempotent consumer eager or when the exchange is done.</li><li>Working
with the Camel source code in Eclipse with m2eclipse plugin improved to avoid
endless file changed detection and recompile the source.</li><li>Add
option <code>suppressExceptions</code> to <a shape="rect"
href="jsonpath.html">JSonPath</a> which allows to ignore exceptions such as
NoSuchPathException when the json payload does not contain the path defined in
the json expression.</li><li><a shape="rect" h
ref="spring-boot.html">Spring Boot</a> now creates <code>CamelContext</code>,
<code>ProducerTemplate</code> and <code>ConsumerTemplate</code> beans only if
those are not defined by the
user.  </li><li>New <code>camel-archetype-spring-boot</code> to
create a new Camel Spring Boot project using
Maven.</li><li>New <code>camel-archetype-cdi</code> to create a new
Camel CDI project using Maven.</li><li><a shape="rect"
href="ftp2.html">FTP2</a> doesn't support absolute directories in endpoint
URIs. In such cases, paths will be treated as relative and WARN message will be
printed in logs. In future versions, there'll be no such assumption and
validation exception will be thrown instead.</li><li><a shape="rect"
href="swagger.html">Swagger</a> module now supports getting api-docs from
multiple camel contexts in the JVM. The entry point at /api-docs now lists the
contexts detected, and you need to append the context id in the path, eg
/api-docs/myCamel</li><li><a shap
e="rect" href="ftp2.html">FTP2</a> supports <code>autoCreate=true</code>
for ftp consumers</li><li><a shape="rect" href="rest-dsl.html">Rest DSL</a> now
supports to define parameter using fine grained details for the <a shape="rect"
href="swagger.html">Swagger</a> api documentation. For an example see
the <code>camel-example-servlet-rest-tomcat</code> in the Apache Camel
distribution.</li><li>The <a shape="rect" href="simple.html">Simple</a>
language now has a equals ignore case operator (=~) when comparing with string
values </li><li>If using <contextScan> with Spring or Blueprint to
filter RouteBuilder classes, then Camel will now by default only look for
singleton beans. You can turn on the old behavior to include prototype scoped
with the new option <pre>includeNonSingletons</pre></li><li>The <a
shape="rect" class="external-link"
href="http://camel.apache.org/maven/current/camel-core/apidocs/org/apache/camel/spi/IdempotentRepository.html";>Idem
potentRepository</a> now supports clear operation, to clear the repository,
and expose it over JMX.</li><li><a shape="rect"
href="netty4.html">Netty4</a> in clientMode will now automatic re-connect
if the connection was disconnected to the

Exchange.</li><li>When using <a shape="rect"
href="expression.html">Expression</a> or <a shape="rect"
href="predicate.html">Predicate</a> in the routes, you can refer to the value
as an external resource by using <strong>resource:classpath:path</strong> or
<strong>resource:file:path</strong> - for example
<code>resource:classpath:com/foo/myscript.groovy</code>.</li><li>Added option
useMessageBodyForSql to the <a shape="rect" href="sql-component.html">SQL
Component</a> which allows to use more dynamic SQL queries inst
ead of the fixed SQL defined in the endpoint uri.</li><li>Added sticky option
to failover <a shape="rect" href="load-balancer.html">Load
Balancer</a> so the load balancer can start from the last known good
endpoint.</li><li>Added option <code>shareUnitOfWork</code> to <a
shape="rect" href="content-enricher.html">Content Enricher</a> eip</li><li><a
shape="rect" href="content-enricher.html">Content Enricher</a> with enrich and
pollEnrich now supports dynamic endpoint uris computed using an <a
shape="rect" href="expression.html">Expression</a> that allows to use values
from the current <a shape="rect" href="exchange.html">Exchange</a> so you
for example can poll a file which name is computed from data from the <a
shape="rect" href="exchange.html">Exchange</a> etc. This change breaks the XML
DSL a little bit and there is an easy migration effort. The Java DSL stays
backwards compatible.</li><li>The Camel Karaf commands about routes now no
longer requir
e the context-id as 2nd parameter that is optional - if none provided then the
command is a bulk operation for all Camel contexts.</li><li>A simpler version

gather additional metrics during runtime.</li><li>All the <a shape="rect"
href="aws.html">Camel-AWS</a> components now support the definition (through
URI options) of Proxy Host and Proxy Port.</li><li>The HTTP based consumers no
longer include Camel headers in the responses by default (they already did this
for the producers to not include Camel headers when calling a HTTP
service).</li><li><a shape="rect" href="bindy.html">Bindy</a> now supports
having multiple pojos as models in the same java package. Instead of
configuring using package names, you configure using class names.</li><li>You
can configure on the <a shape="rect" href="type-converter.html">Type
Converter</a> registry what should happen if a duplicate type converter is
being added (override, ignore or fail) as well configure the logging
level.</li><li><a shape="rect" href="using-camelproxy.html">Using
CamelProxy</a> now binds the method para
meters to the message body/header using Camel annotations to define the

HTTP</a>, <a shape="rect" href="netty
4-http.html">Netty4 HTTP</a>, and <a shape="rect"
href="jetty.html">Jetty</a> components for their producers. The default range
is 200-299.</li><li>Now <a shape="rect"

consumers</a>. </li><li>Support for TAR files: marshalling and
unmarshalling via a data format; splitting; aggregating. See <em>Data
Formats</em> section below.</li><li><a shape="rect" href="sjms.html">SJMS</a>
component has been aligned to bind between Camel Message and JMS Message in the
same way as <a shape="rect" href="jms.html">JMS</a> component does
that.</li><li>Added failsafe check to ensure <a shape="rect"
href="jms.html">JMS</a> consumer will no longer send back a reply message to
the same destination as itself to avoid endless loop. There is an option to

id="Camel2.16.0Release-Importantchangestoconsiderwhenupgrading">Important
changes to consider when upgrading</h2><ul><li>The dumpRoutesAsXml operation
now preserve property placeholder used in the route models. </li><li>Using
setFaultBody / setFaultHeader behaves similar to
setBody / setHeader to preserve existing headers/attachments by setting on
existing IN or OUT message.</li><li>If using concurrent consumer on <a
shape="rect" href="jms.html">JMS</a> endpoints for request/reply over JMS
then you must use the new replyToConcurrentConsumers,
replyToMaxConcurrentConsumers options to configure the
values. </li><li>When the <a shape="rect"
href="aggregator2.html">Aggregator2</a> is forced completed the exchange
property <code>Exchange.AGGREGATED_COMPLETED_BY</code> value has been
changed from "forceCompletion" to "force" so its named like the other
completion triggers.</li><li>Removed unsupported modules camel-web and
camel-web-standalone.</li><li>Removed unsupported camel:dot functionality from
camel:run plugin.</li><li>Removed unsupported camel-archetype-scala-component
from maven archetypes.</li><li>The Maven coordinate for linkedin and olingo2
components changed to be aligned like all the others having groupId as just
org.apa
che.camel.</li><li>If using MongoDB component, the option<em>
invokeGetLastError</em> doesn't exist anymore. The option invokeGetLastError
instructs the MongoDB Java driver to invoke <em>getLastError()</em> after every
call. In the 3.0.0 MongoDB driver implementation, the <em>getLastError()</em>
method in WriteResult has been removed. So, if needed, use an acknowledged
WriteConcern when executing the write operation and then verify the correctness
of the operation with the method <em>wasAcknowledged()</em> of
WriteResult.</li><li>The <a shape="rect" href="jing.html">Jing</a>
component now uses <code>jing</code> as schema name in uris, instead
of <code>rng</code> or <code>rnc</code>. Those names has been
removed.</li><li><a shape="rect" href="swagger.html">Swagger</a> module now
supports getting api-docs from multiple camel contexts in the JVM. The entry
point at /api-docs now lists the contexts detected, and you need to append the
context id in the path, eg /api-
docs/myCamel</li><li>If using <contextScan> with Spring or Blueprint to
filter RouteBuilder classes, then Camel will now by default only look for
singleton beans. You can turn on the old behavior to include prototype scoped
with the new
option <pre>includeNonSingletons</pre></li><li>camel-vertx has been
upgraded to vertx 3.0 which requires Java 8 at
runtime.</li><li><code>camel-cdi</code> is now using CDI 1.1 api - support for
1.0 has been dropped.</li><li><a shape="rect"
href="content-enricher.html">Content Enricher</a> with enrich and pollEnrich
now supports dynamic endpoint uris computed using an <a shape="rect"
href="expression.html">Expression</a> that allows to use values from the
current <a shape="rect" href="exchange.html">Exchange</a> so you for
example can poll a file which name is computed from data from the <a
shape="rect" href="exchange.html">Exchange</a> etc. This change breaks the XML
DSL a little bit and there is an easy migration effor
t. The Java DSL stays backwards compatible.</li><li>Support for CXF 2.7 is
dropped.</li><li>camel-jetty8 is being considered deprecated and we would like
to drop this in a nearby future release as Jetty 8.x is EOL. </li><li>If
you have explicit configured the JMX statistics level to All then that option
is now called Default. </li><li>The HTTP based consumers no longer include
Camel headers in the responses by default (they already did this for the
producers to not include Camel headers when calling a HTTP service).</li><li><a
shape="rect" href="bindy.html">Bindy</a> requires to be configured using class
names instead of package names, as it now supports having multiple model
classes in the same java packages now.</li><li><a shape="rect"
href="using-camelproxy.html">Using CamelProxy</a> now binds the method
parameters to the message body/header using Camel annotations to define the
binding rules. If no annotations is defined the the parameter is assumed the
message body. Y
ou can turn this off to have the old behavior.</li><li><a shape="rect"
href="sjms.html">SJMS</a> component has been aligned to bind between Camel
Message and JMS Message in the same way as <a shape="rect"
href="jms.html">JMS</a> component does that, in the process a few APIs and
behavior has been changed.</li><li><code>DefaultExchangeHolder</code> now
only keep primitive / String type headers / exchange properties (like JMS
component) and filter out other types such as java instances (caught exception
on exchange property is kept as well).</li></ul><h2

the 2.16.0 release which approx XXX issues resolved (new features, improvements
and bug fixes such as...)</p><p>Noteworthy improvements:</p><ul><li>The route
models (definition classes) preserve property placeholders, which allows round
trip editing, and also prevents showing potential sensitive
information</li><li>Added onPrepareFailure option to <a shape
="rect" href="dead-letter-channel.html">Dead Letter Channel</a> to allow a
custom processor to prepare the Exchange before sending to the dead letter
queue.</li><li><a shape="rect" href="mongodb.html">MongoDB</a> tailable
consumers now allow setting the <code>readPreference</code>
option.</li><li>Using setFaultBody / setFaultHeader behaves similar to setBody
/ setHeader to preserve existing headers/attachments by setting on existing IN
or OUT message.</li><li>Java DSL using choice with end vs endChoice now
validates you use them as intended. Any misconfiguration now throws an
exception explaining the problem.</li><li><a shape="rect"
href="pojo-producing.html">POJO Producing</a> and <a shape="rect"
href="pojo-consuming.html">POJO Consuming</a> lifecycle is now in sync with <a
shape="rect" href="camelcontext.html">CamelContext</a> which ensures it
works as similar to Camel <a shape="rect" href="routes.html">Routes</a>
does. Also the created producer/consumer is stopped
when <a shape="rect" href="camelcontext.html">CamelContext</a> is
stopping to cleanup properly.</li><li><a shape="rect"
href="jms.html">JMS</a> component now allows configuring
concurrentConsumers/maxConcurrentConsumers separately between from(jms) vs
to(jms) using request/reply over JMS</li><li><span><a shape="rect"
class="external-link"
href="https://issues.apache.org/jira/browse/CAMEL-8506";>Added SEARCH</a>
operation to Elasticsearch component</span></li><li><span>The <a
shape="rect" href="properties.html">Properties</a> component (property
placeholder) now supports an encoding option to allow reading the .properties
files using a specific charset such as UTF-8. By default ISO-8859-1 is used
(latin1)</span></li><li><span>Added <code>receviveBufferSize</code> option
to the <a shape="rect" href="ftp.html">FTP</a> component to make download
faster. The size is by default 32kb buffer.</span></li><li><span>The <a
shape="rect" href="aggregator2.html">
Aggregator2</a> EIP now allows an external source using
a <code>AggregateController</code> to control the aggregator, such as for
forcing completing a group or all groups, or query runtime information from the
aggregator. A default controller is provided out of the box if none has been
configured.</span></li><li><span>The <a shape="rect"
href="aggregator2.html">Aggregator2</a> now enlists in JMX using
a <code>ManagedAggregateProcessorMBean</code> which has more information,
and also allows using the aggregate controller to control
it.</span></li><li><span>The <a shape="rect"
href="aggregator2.html">Aggregator2</a> now includes more runtime statistics
which can be accessed from Java and JMX about number of incoming and completed
exchanges, and per different completion
triggers.</span></li><li><span>The <a shape="rect"
href="aggregator2.html">Aggregator2</a> now supports pre-completion mode if the
aggregation strategy implements <code>PreCompletionAwareAg
gregationStrategy</code>. This supports the use-case where an incoming
Exchange are used to determine if the current aggregated group is completed or
not. If completed the group is emitted as-is, and the new incoming Exchange is
used to start a new group from scratch.</span></li><li><span>Added options
to <a shape="rect" href="mail.html">Mail</a> consumer so it can skip or
handle a mail message that cannot be read from the mail server in the batch;
and then move on to read the next message. This ensures the consumer can deal
with mail boxes that has problematic mails that otherwise will cause no mails
to be retrieve by the consumer in the batch.</span></li><li>The runtime route
processors and their corresponding model definition are now linked by their id
using <code>HasId</code>, so its easier to obtain the processor or model
definition from the <code>getProcessor(id)</code> and
<code>getProcessorDefintion(id)</code> api on
CamelContext.</li><li>CamelContext now also
includes a getManagedProcessor API to easily get the mbean client api for the
processor, so you can access the runtime JMX statistics from Java
code. </li><li><span><a shape="rect" href="spring-boot.html">Spring

call. In the 3.0.0 MongoDB driver implementation, the <em>getLastError()</em>
method in WriteResult has been removed. So, if needed, use an acknowledged
WriteConcern when executing the write operation and then verify the correctness
of the operation with the method <em>wasAcknowledged()</em> of
WriteResult.</li><li>The <a shape="rect" href="jing.html">Jing</a>
component now uses <code>jing</code> as schema name in uris, instead
of <code>rng</code> or <code>rnc</code>. Those names has been
removed.</li><li><a shape="rect" href="swagger.html">Swagger</a> module now
supports getting api-docs from multiple camel contexts in the JVM. The entry
point at /api-docs now lists the contexts detected, and you need to append the
context id in the path, eg /api-
docs/myCamel</li><li>If using <contextScan> with Spring or Blueprint to
filter RouteBuilder classes, then Camel will now by default only look for
singleton beans. You can turn on the old behavior to include prototype scoped
with the new
option <pre>includeNonSingletons</pre></li><li>camel-vertx has been
upgraded to vertx 3.0 which requires Java 8 at
runtime.</li><li><code>camel-cdi</code> is now using CDI 1.1 api - support for
1.0 has been dropped.</li><li><a shape="rect"
href="content-enricher.html">Content Enricher</a> with enrich and pollEnrich
now supports dynamic endpoint uris computed using an <a shape="rect"
href="expression.html">Expression</a> that allows to use values from the
current <a shape="rect" href="exchange.html">Exchange</a> so you for
example can poll a file which name is computed from data from the <a
shape="rect" href="exchange.html">Exchange</a> etc. This change breaks the XML
DSL a little bit and there is an easy migration effor
t. The Java DSL stays backwards compatible.</li><li>Support for CXF 2.7 is
dropped.</li><li>camel-jetty8 is being considered deprecated and we would like
to drop this in a nearby future release as Jetty 8.x is EOL. </li><li>If
you have explicit configured the JMX statistics level to All then that option
is now called Default. </li><li>The HTTP based consumers no longer include
Camel headers in the responses by default (they already did this for the
producers to not include Camel headers when calling a HTTP service).</li><li><a
shape="rect" href="bindy.html">Bindy</a> requires to be configured using class
names instead of package names, as it now supports having multiple model
classes in the same java packages now.</li><li><a shape="rect"
href="using-camelproxy.html">Using CamelProxy</a> now binds the method
parameters to the message body/header using Camel annotations to define the
binding rules. If no annotations is defined the the parameter is assumed the
message body. Y
ou can turn this off to have the old behavior.</li><li><a shape="rect"
href="sjms.html">SJMS</a> component has been aligned to bind between Camel
Message and JMS Message in the same way as <a shape="rect"
href="jms.html">JMS</a> component does that, in the process a few APIs and
behavior has been changed.</li><li><code>DefaultExchangeHolder</code> now
only keep primitive / String type headers / exchange properties (like JMS
component) and filter out other types such as java instances (caught exception
on exchange property is kept as well).</li></ul><h2
