Comment #13 on issue 597 by twr....@gmail.com: Persist Extension:
UnitOfWork.begin() throws IllegalStateException when called multiple times
http://code.google.com/p/google-guice/issues/detail?id=597
I encountered the same issue with JpaPersistService.end() and would like it
to be addressed. How likely is it that the fix suggested in the previous
post would end up in a new release?
Problem:
If an exception is thrown in
com.google.inject.persist.jpa.JpaPersistService.end() on em.close(),
entityManager.remove() is not called.
When used from com.google.inject.persist.PersistFilter, this results in
java.lang.IllegalStateException for every consequent invocation of the
filter.
1) exception on em.close()

2) exception on filter invocation
java.lang.IllegalStateException: Work already begun on this thread. Looks
like you have called UnitOfWork.begin() twice without a balancing call to
end() in between.
