I don't think I have a good enough understanding of JPA to explain what I mean. Maybe something like this: em = getEmFromFactory(); EntityB b = getBFromQuery(em); EntityA a = new EntityA(); a.setB(b); Thread.sleep(1000); em.persist(a); If two threads enter this code overlapping by a few millis, could "b" fail due to it being managed by the other thread's em? I figure if the problem with my code resulted in an em being left open and this error being thrown, then there might be a race condition present even after fixing the problem in my code, just with a smaller window. -- Daryl Stultz _____________________________________ 6 Degrees Software and Consulting, Inc. http://www.6degrees.com mailto:[email protected]
