> 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,
>    Wolfgang
