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 Ch
annel</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">Cam
elContext</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 usin
g 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>PreCompletionAwareAggregationStrategy</code>. This
supports the use-case w
here 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

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</code> converter</a></span></span></li><li><span>Ability

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 support 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 <co
de>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 are 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

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" href="spring-boot.html">Spring
Boot</a> now creates <co
de>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></ul><p>Fixed the following
issues:</p><ul><li>File language now properly supports file extensions having
double dots, such as .tar.gz</li><li>Fixed issue with doTry not stopping
routing if a fault message was set using setFaultBody within the

messages, but each sub message has its own unique message id (just as the
exchange has).</li><li>Fixed an issue with the circuit breaker <a
shape="rect" href="load-balancer.html">Load Balancer</a> not honoring the half
open after period after an error was detected.</li><li>Fixed <a
shape="rect" href="ftp2.html">FTP2</a> now calling disconnect if there was no
messages to poll, even when disconnect=true configured.</

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.
0;</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 change
d to be aligned like all the others having groupId as just
org.apache.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></ul><h2 id="Camel2.16.0Release-GettingtheDistributions">Getting

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

id="Camel2.16.0Release-Importantchangestoconsiderwhenupgrading">Important
changes t
o 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 unsuppo
rted 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.apache.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></ul><h2 id="Camel2.16.0Release-GettingtheDistribution
