Major Description
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
