garpinc commented on OPENJPA-2399:
----------------------------------
I'm not so sure as I also get the problem when doing api driven build time
enhancement with PCEnhancer.run(ojc, eargs, eflags, null, writer,
classLoader);
The error I get is slightly different than yours Rick and it occurs when
creating the EntityManager long after the enhancement has already been done.
I'm using jdk1.7.0_10 and here is my stack trace.
