Konrad Windszus updated FELIX-6549:
-----------------------------------
Description:
When the SCR Bnd Plugin is used with JRE 11 the service descriptor XMLs contain
a lot of empty lines:
{code}
<?xml version="1.0" encoding="UTF-8"?>
<scr:component xmlns:scr="http://www.osgi.org/xmlns/scr/v1.1.0";
name="org.apache.jackrabbit.oak.composite.CrossMountReferenceValidatorProvider"
configuration-policy="require" activate="activate">
<property name="type" value="crossMountRefValidator"/>
<property name="failOnDetection" type="Boolean" value="true"/>
<service servicefactory="false">
<provide
interface="org.apache.jackrabbit.oak.spi.commit.ValidatorProvider"/>
<provide
interface="org.apache.jackrabbit.oak.spi.commit.EditorProvider"/>
</service>
<reference name="mountInfoProvider"
interface="org.apache.jackrabbit.oak.spi.mount.MountInfoProvider"
cardinality="1..1" policy="static" bind="bindMountInfoProvider"
unbind="unbindMountInfoProvider"/>
<implementation
class="org.apache.jackrabbit.oak.composite.CrossMountReferenceValidatorProvider"/>
</scr:component>
{code}
With JRE 8 the XML looked like this with the same version of the Bnd SCR plugin
{code}
<?xml version="1.0" encoding="UTF-8"?>
<scr:component xmlns:scr="http://www.osgi.org/xmlns/scr/v1.1.0";
name="org.apache.jackrabbit.oak.composite.CrossMountReferenceValidatorProvider"
configuration-policy="require" activate="activate">
<property name="type" value="crossMountRefValidator"/>
<property name="failOnDetection" type="Boolean" value="true"/>
<service servicefactory="false">
<provide
interface="org.apache.jackrabbit.oak.spi.commit.ValidatorProvider"/>
<provide
interface="org.apache.jackrabbit.oak.spi.commit.EditorProvider"/>
</service>
<reference name="mountInfoProvider"
interface="org.apache.jackrabbit.oak.spi.mount.MountInfoProvider"
cardinality="1..1" policy="static" bind="bindMountInfoProvider"
unbind="unbindMountInfoProvider"/>
<implementation
class="org.apache.jackrabbit.oak.composite.CrossMountReferenceValidatorProvider"/>
</scr:component>
{code}
It seems that a different SAX {{Transformer}} is returned at
https://github.com/apache/felix-dev/blob/28b4c77883b8dbdea06e723dc4e5a3eba7393f34/tools/org.apache.felix.scr.generator/src/main/java/org/apache/felix/scrplugin/xml/IOUtils.java#L70
which already emits the newlines due to the "INDENT" flag.
was:
When the SCR Bnd Plugin is used with a recent Bnd version (6.3.1) used in
maven-bundle-plugin 5.1.7 the service descriptor XMLs contain a lot of empty
lines:
{code}
<?xml version="1.0" encoding="UTF-8"?>
<scr:component xmlns:scr="http://www.osgi.org/xmlns/scr/v1.1.0";
name="org.apache.jackrabbit.oak.composite.CrossMountReferenceValidatorProvider"
configuration-policy="require" activate="activate">
<property name="type" value="crossMountRefValidator"/>
<property name="failOnDetection" type="Boolean" value="true"/>
<service servicefactory="false">
<provide
interface="org.apache.jackrabbit.oak.spi.commit.ValidatorProvider"/>
<provide
interface="org.apache.jackrabbit.oak.spi.commit.EditorProvider"/>
</service>
<reference name="mountInfoProvider"
interface="org.apache.jackrabbit.oak.spi.mount.MountInfoProvider"
cardinality="1..1" policy="static" bind="bindMountInfoProvider"
unbind="unbindMountInfoProvider"/>
<implementation
class="org.apache.jackrabbit.oak.composite.CrossMountReferenceValidatorProvider"/>
</scr:component>
{code}
With Bnd 5.1.1 (used in maven-bundle-plugin 5.1.1) the XML looked like this
with the same version of the Bnd SCR plugin
{code}
<?xml version="1.0" encoding="UTF-8"?>
<scr:component xmlns:scr="http://www.osgi.org/xmlns/scr/v1.1.0";
name="org.apache.jackrabbit.oak.composite.CrossMountReferenceValidatorProvider"
configuration-policy="require" activate="activate">
<property name="type" value="crossMountRefValidator"/>
<property name="failOnDetection" type="Boolean" value="true"/>
<service servicefactory="false">
<provide
interface="org.apache.jackrabbit.oak.spi.commit.ValidatorProvider"/>
<provide
interface="org.apache.jackrabbit.oak.spi.commit.EditorProvider"/>
</service>
<reference name="mountInfoProvider"
interface="org.apache.jackrabbit.oak.spi.mount.MountInfoProvider"
cardinality="1..1" policy="static" bind="bindMountInfoProvider"
unbind="unbindMountInfoProvider"/>
<implementation
class="org.apache.jackrabbit.oak.composite.CrossMountReferenceValidatorProvider"/>
</scr:component>
{code}
It seems that a different SAX {{Transformer}} is returned at
https://github.com/apache/felix-dev/blob/28b4c77883b8dbdea06e723dc4e5a3eba7393f34/tools/org.apache.felix.scr.generator/src/main/java/org/apache/felix/scrplugin/xml/IOUtils.java#L70
which already emits the newlines due to the "INDENT" flag. Maybe Bnd embeds
one, because I reproduced with the same JRE 11.0.15.
