> Hello,
> The problem may come from class loading issue, I've tried with both OpenJPA
> 1.2.0 and 1.2.1. Debugging the Maven build, the load of the persistence file
> by the PersistenceProductDerivation is done two times, first by a class
> loader wich finds the resource META-INF/test/persistence.xml, and second by
> another class loader wich fails to find the resource. The class loaders are
> stringfied as:
> ClassRealm[maven.plugin.openjpa, parent:
> ClassRealm[/plugins/org.codehaus.mojo:openjpa-maven-plugin:1...@-2084258001/thread:main,
> parent: ClassRealm[plexus.core, parent: null]]]
> ClassRealm[/plugins/org.codehaus.mojo:openjpa-maven-plugin:1...@-2084258001/thread:main,
> parent: ClassRealm[plexus.core, parent: null]]
> I am not a class loading expert so I don't figure what is happening, but it
> seems a problem in the class loading hierarchy. I have also tried to specify
> the persistence unit as META-INF/test/persistence.xml#TestUnit, but the
> problem persists. The resulting stack trace is:
