karaf-maven-plugin generates another org.apache.karaf.features.xml with Java 8/Java 11
Hi all,
I tried to create my custom Karaf distribution (using karaf-maven-plugin
4.3.2) with Java 11 for the first time, and I noticed a difference in the
resulting org.apache.karaf.features.xml
The line
<featuresProcessing xmlns="
http://karaf.apache.org/xmlns/features-processing/v1.0.0" xmlns:f="
http://karaf.apache.org/xmlns/features/v1.6.0">
has been changed into
<ns3:featuresProcessing xmlns:ns2="
http://karaf.apache.org/xmlns/features/v1.6.0" xmlns:ns3="
http://karaf.apache.org/xmlns/features-processing/v1.0.0">
which means a namespace has been added. Unfortunately this little change
has a big impact because now my app immediately runs OutOfMemory when I
start Karaf. There is very little DEBUG-logging, the behaviour is somewhat
like described in https://issues.apache.org/jira/browse/KARAF-6068
Removing the namespace fixes the problem.
Do you have any idea how I can prevent my app from going OOM after this
change ? Or how I can prevent the namespace from being added with Java 11 ?
It would be nice to understand the exact problem here.
Kind regards,
Steven

Hi JB,
Adding
<dependencies>
<dependency>
<groupId>org.glassfish.jaxb</groupId>
<artifactId>jaxb-runtime</artifactId>
<version>2.3.0</version>
</dependency>
</dependencies>
to the plugin did not have any effect, the
resulting org.apache.karaf.features.xml still contains the namespace prefix.
Kind regards,
Steven

Hi JB,
I'm not overriding any dependencies for the plugin. I do list
mvn:org.apache.servicemix.bundles/org.apache.servicemix.bundles.jaxb-impl/2.2.6_1
in the feature.xml of my application, but I assume that is not what you are
referring to.
Romain suggested to override the jaxb dependency version, but I cannot find
how to do this. I didn't find any jaxb dependency in the github-code for
the karaf-maven-plugin. Any suggestion ?
Best regards,
Steven

Hi
Do you use jaxb version provided by the plugin ou you define your own jaxb version ?

Hi JB,
We're not using the generate-features-MOJO either, the feature.xml has been
written by hand. But by using the assembly-MOJO, the
etc\org.apache.karaf.features.xml is generated, which I can also see in
the logging :
*22:43:01,512 [INFO] Generating features processor configuration:
etc\org.apache.karaf.features.xml*
I think the prefixes should be OK indeed, but it would be nice to leave
them out while looking for a solution for the other problem.
Below you can find the stacktrace from the OOM, I also have a list of
Objectsin my heapdump :

Hi Steven,
Let me try to reproduce on a simple test case.
I don’t see yet the relationship between the prefixes generated (which are not bad IMHO) and the OOM (I’m suspecting more like a loop in the features XML definition).
Just a reminder: in Karaf itself, we don’t use the generate-features MOJO, we write the features XML/JSON by hand (largely better to have a complete control).
Regards

Re: karaf-maven-plugin generates another org.apache.karaf.features.xml with Java 8/Java 11
Posted by Steven Huypens <st...@gmail.com>.
Hi Bernd,
That's what I did :
1) Compile all code with Java 8, create distro with Java 8, run with Java 8
--> Works
2) Compile all code with Java 8, create distro with Java 8, run with Java
11 --> Works
3) Compile all code with Java 8, create distro with Java 11, run with Java
11 --> Doesn't work, app goes OOM
4) Compile all code with Java 11, create distro with Java 11, run with Java
11 --> Doesn't work, app goes OOM
The only difference between (2) and (3) is the prefix in
org.apache.karaf.features.xml, and if I remove that manually, the app works
as expected. I also think the generated org.apache.karaf.features.xml is
OK, but I have no clue why the application goes OOM with it.
Kind regards,
Steven

Posted by Bernd Eckenfels <ec...@zusammenkunft.net>.
Yes looked in the wrong Schema. I think, don’t worry about the prefixes, as long as the elements are correctly qualified (the processing elements in your case with ns3:) they are equivalent. Your memory problems have likely another cause. But as stated, it might be a good idea to list the repos and features in both running instances and compare them, just to be sure.
(Besides the maven plugin probably should define a few fixed prefixes to make it better readable)
Not sure why the maven plug-in is so sensitive to the jaxb version (if executed with java11 it needs to provide its own). Can you maybe run both builds with the same JDK?
Gruss
Bernd

Hi Bernd,
- I do see 'blacklistedRepositories' in
http://karaf.apache.org/xmlns/features-processing/v1.0.0
- With the namespace-prefix my app goes OOM immediately, so I cannot
compare both running systems.
- I tried adding the prefix to each child, but that did not help
Kind regards,
Steven

In that case, it’s weird as Karaf uses jdk11 to build and I don’t see such issue.
Do you have a test repo where I can take a look ?
Thanks

Re: karaf-maven-plugin generates another org.apache.karaf.features.xml with Java 8/Java 11
Posted by Steven Huypens <st...@gmail.com>.
Hi,
I found out package-info.java in the
package org.apache.karaf.features.internal.model.processing contains
@XmlSchema(namespace =
"http://karaf.apache.org/xmlns/features-processing/v1.0.0",
elementFormDefault = XmlNsForm.QUALIFIED, attributeFormDefault
= XmlNsForm.UNQUALIFIED,
xmlns = {
@XmlNs(prefix = "", namespaceURI = FEATURES_PROCESSING_NS),
@XmlNs(prefix = "f", namespaceURI =
FeaturesNamespaces.URI_CURRENT)
}
)
These annotations are ignored when using Java 11, I have no idea why, but
looks like a bug to me.
Kind regards,
Steven

Re: karaf-maven-plugin generates another org.apache.karaf.features.xml with Java 8/Java 11
Posted by Steven Huypens <st...@gmail.com>.
Hi Bernd,
I must correct myself. Adding the 'ns3'-prefix to all of the children does
help. It seems all of the tags without prefix are ignored at boot-time
which causes the OOM. So maybe a fix in the karaf-maven-plugin would be
best, the prefix should be added to each child...
Kind regards,
Steven

Hi Bernd,
- I do see 'blacklistedRepositories' in
http://karaf.apache.org/xmlns/features-processing/v1.0.0
- With the namespace-prefix my app goes OOM immediately, so I cannot
compare both running systems.
- I tried adding the prefix to each child, but that did not help
Kind regards,
Steven

In that case maybe the child (deny* list?) is ignored, not sure how strict the parser is in regards to namespaces. I don’t see a blacklistRepository element in the Schema anyway. It’s maybe best you inspect the running systems with feature:* commands and look for differences.

Hi Bernd,

I'm sorry but I do not understand what you mean. You think part of my

blacklistedFeatures en blacklistedBundles which would cause problems if

Hello Steven
How do the child elements of that element look like? Are they using default/f/ns2 prefix and maybe the (semantically equivalent) change affects your memory only because the old form ignored a actual entry for dependency?

Maybe force jaxb version to an earlier one in karag pluhin dependencies in
