Summary: JDBCOptimisticLocking NullPointerException on remove
Initial Comment:
I am using 3.2.0 RC3 and have a an entity bean with a
one to many relation with another entity bean. Both
uses Optimistic Locking with modified strategy. They
are tagged for cascade delete and when I do a remove on
the ParentBean I get the following error:

Hi Alex,
Thanks for looking into it. Currently with RC4 and
optimistic locking (modified and Timestamp starategies
tested) the error is as follow:

Unfortunately, I found the stacktrace not corresponding to the
current source code. But I did see the problem with CMR
fields with foreign key fields (like in your case).
I don't know, though, the reason for NPE.
I fixed the problem I've found. As soon as I am able, I'll
commit the fix.
Thanks,
alex
