NullPointerException when mapping enum field
Hi
I am getting
NullPointerException during EM initialization. I am not using JPA
annotations, just mappings file (see attachment).
In my orm.xml
file, I have an entity with enum field mapped as
<enumerated>STRING</enumerated>. The exception I am getting
is:
...

I think there
might be a bug in EclipseLink as this is working when using EL
1.1.0. Thanks.
