Re: Performance Signature Plugin: JAXB API is missing with Java 11

That's strange. JAXB should be bundled in Docker.

Raphael Pionke any chance you are passing custom JAVA_OPTS?

FTR, I just started a fresh container using jenkins/jenkins:jdk11 image, and docker exec shows the following:

ps aux | grep java
jenkins      9  131 14.2 9939268 2280448 ?     Sl   11:25   0:59 java -p /usr/share/jenkins/ref/java_cp/jaxb-api.jar:/usr/share/jenkins/ref/java_cp/javax.activation.jar: --add-modules java.xml.bind,java.activation -cp /usr/share/jenkins/ref/java_cp/jaxb-impl.jar:/usr/share/jenkins/ref/java_cp/jaxb-core.jar -Duser.home=/var/jenkins_home -jar /usr/share/jenkins/jenkins.war --enable-future-java

Raphael Pionke in addition to Oleg's question, could you please do the same inside your container and show us what your ps aux | grep java looks like?

Thank you!

I tested the new release of the JAXB Plugin and it works with and without a container. I will release the plugin in the next few days.

Thanks a lot for your effort!

Re: Performance Signature Plugin: JAXB API is missing with Java 11

Raphael Pionke Jenkins 2.163 has been released with the core JAXB patch, see https://jenkins.io/changelog/#v2.163

It would be great if you can test the current last 3.1.0 release of your plugin on Jenkins 2.163 on a Java 11 runtime, and report here the outcome.

This should work without issue.

Thanks!

Raphael Pionke I'm trying to find a solution on this but it seems that I'm failing to reproduce the problem. 

When I try to install the plugin on Jenkins running on Java 8 and on Java 11, the JAXB plugin is installed automatically. The only difference is that I'm using Jenkins 2.164.1 version, not 2.163. 

Do you have any update on the subject?

Adrien Lecharpentier yeah i know. The JAXB Plugin is installed and loaded correctly. I don't understand that either.

I created a reproducer in this ticket: https://issues.jenkins-ci.org/browse/JENKINS-56265

Raphael Pionke I finally found out what is happening here. The retrofit2 library, using JAXB, is not providing a context to JAXB to parse the response. Because of this, JAXB tries to find a context (see here). As it is failing to find one, it falls back to a platform default one: the com.sun.xml.internal.bind.v2.ContextFactory, which doesn't exist in Java 11.

Know that I see what is happening, I'm trying to find a solution.

Hi Adrien Lecharpentier, i seems to be that the class com.sun.xml.internal.bind.v2.ContextFactory is not found by the ContextFinder.find method. To test this i created a jaxb.properties file with the following content: 

javax.xml.bind.context.factory=com.sun.xml.bind.v2.ContextFactory

The class should be in the class path, cause the jaxb-plugin is providing the class via the jaxb-impl maven dependency. So the real question is why is this class not found, but provided?

I am about the same, just that I used the system property over the jaxb.properties file. Result is the same.

I'm afraid this is because of the fact that the JAXB requirement is not in the plugin but in th Retrofit2 library used by the plugin.

I tested the same configuration on the Sloccount plugin and it's working fine on this plugin. I run in both case mvnDebug -Djenkins.version=2.164.1 -Djavax.xml.bind.context.factory=com.sun.xml.bind.v2.ContextFactory hpi:run (with -pl dynatrace-appmon here) and for sloccount I could get it to work fine (not going into the catch here) and in Performace Signature Dynatrace I still have the same exception.

The "only" difference between the two plugins is that JAXB is a transitive dependency here but not in Sloccount plugin. It makes no sense. I can see in both case the JAXB plugin installed on the instance. I can even run import com.sun.xml.bind.v2.ContextFactory; in the script console of both instances and it's working fine.

I'm that the retrofit library is creating the problem: https://github.com/square/retrofit/blob/fc14b32026a5a7b487f27483c18b2263d84bcf60/retrofit/src/main/java/retrofit2/Retrofit.java#L134.

As mentioned in java9.wft/class-loading, this could be prevented by using ClassLoader.getPlatformClassLoader which is only available in Java 9+.

I tried to use the moxy implementation of jaxb by using the org.eclipse.persistence:eclipselink:2.7.4 maven dependency in the dynatrace-appmon maven module and a jaxb.properties file with the following content:

javax.xml.bind.context.factory=org.eclipse.persistence.jaxb.JAXBContextFactory

Same result, i get the following exception:

javax.xml.bind.JAXBException: Implementation of JAXB-API has not been found on module path or classpath.
 - with linked exception:
[java.lang.ClassNotFoundException: org.eclipse.persistence.jaxb.JAXBContextFactory]

So, it has to be something to do with the transitive dependency i think, cause the direct calls from the [Unit tests|https://github.com/jenkinsci/performance-signature-dynatrace-plugin/blob/master/dynatrace-appmon/src/test/java/de/tsystems/mms/apm/performancesignature/dynatrace/rest/xml/DashboardXMLHandlerTest.java] are working in a java 11 environment.

javax.xml.bind.JAXBException: Implementation of JAXB-API has not been found on module path or classpath.
- with linked exception:
[java.lang.ClassNotFoundException: org.eclipse.persistence.jaxb.JAXBContextFactory]{noformat}

So, it has to be something to do with the transitive dependency i think, cause the direct calls from the [Unit tests|

Raphael Pionke I don't know what change in the classpath or how the class are loaded, but in step-by-step debug of the test you added, I'm going through methods of Retrofit lib that I didn't see in the "real case" usage.

Adrien Lecharpentier do you think, i might help to just get rid of the com.squareup.retrofit2:converter-jaxb dependency and copy those 4 classes into the dynatrace-appmon module?

Raphael Pionke at this moment, I trully believe that getting ride on this dependency is the better solution. You could still be using another converter.
