Hello all,

I'm facing an issue when upgrading from EclipseLink 2.2 to 2.3 (same issue with 2.4 and 2.5-M1).
Predeployment of my PersistenceUnit failed with a Null Pointer Exception on merging orm descriptors.

This happens when I have both the default META-INF/orm.xml descriptor and a custom one (defined in the PU descriptor) defining a PU default entity-listener element on the same class.

Kindly find bellow the stacktrace.

I can provide you a sample project that reproduce it.

Regards,
Loïc
