[eclipselink-users] NPE on entity-listeners metadata merging
|
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
