Wolfgang Glas commented on OPENJPA-1918:
----------------------------------------
Second version works for me, too ;-)
In apache-karaf the standard context class laoder is a boot delegation class
loader from teh framework essentially exposing system and framework classes.
The bundle class loader ait atop of this boot delgation class loader, so the
order in your patch should not cause majot headaches insode apache-karaf.
Sorry for setting the issue to resolved so fast :-/

> Project: OpenJPA
> Issue Type: Bug
> Components: kernel
> Affects Versions: 2.0.1
> Environment: apache-karaf-2.1.0, openjdk-1.6.0b20
> Reporter: Wolfgang Glas
> Assignee: Rick Curtis
> Fix For: 2.1.0

> We are using openjpa inside an OSGi container together with
> openjpa.MetaDataRepository" value="Preload=true"
> We pass the appliation class loeader as part of our PersistenceUnitInfo
> implementation by returning it from PersistenceUnitInfo.getClassLoader().
> However, the code in MetaDataRepository.preload() only uses the context class
> loader and not the class loader from PersistenceUnitInfo, which leades to
> ClassNotFoundExpcetions like mentioned at the end of this report.
> A fix might be quite easily establihed by appending the return value of
> PersistenceUnitInfo.getClassLoader() to the list of claas loaders
> participating in the MultiClassLoader set up in
>
> MetaDataRepository.java:310ff
> In the meanwhile, we are additionally setting our classloader as context
> loader during the creation of the EntityManagerFactory by
> PersistenceProvider.createContainerEntityManagerFactory(), but a fix in
> MetaDatRepository.preload() is highly appreciated.
> TIA for fixing this,
