I guess when I same same problem I mean it displays the same symptoms as what were exhibited under 1.0.1 with sun jdk and the test case attached to original jira item. I tried the original jira item using 1.0.2 on both sun and ibm's jdks and that specific test case works. My application produces an eventual OutOfMemory Exception listed below from a javacore, and as mentioned in the bug the loop runs forever. Not sure how I can reproduce the exact situation to cause this to occur in a sample use case.

Now as far as differences in jvm's I tried with both sun and ibm. Sun: Couldn't even run the enhancer ant script I had setup as it ran out of memory in the same spot. IBM: able to enhance the entities, but OOME at runtime as above. Any suggestions on what you need to help diagnose as far as object relationships,etc. and I will try to provide. But as my application contains a very large number of entities it is hard to tell which relationship is causing the issue. So Re: Bug 258 revisited Kevin Sutter to: users 03/04/2008 12:15 PM Please respond to users Jeff, What aspect of OPENJPA-258 are you experiencing? The OOME? Does your scenario mimic the scenario in 258, or something similar? Or, is there some other aspect of 258 that you are referring to? It's interesting that the scenario described in 258 was not resolved until 1.0.2. And, since you just moved to 1.0.2 and are now experiencing the "same problem" that was supposedly fixed in 1.0.2, then I wonder whether we are talking about the same problem. You mention the IBM JDK. Are you indicating that the problem does not surface with the Sun JDK? That should be a relatively simple verification. I switch back and forth between the IBM and Sun JDK's all the time. If you can provide more details on the specific problem and environment for your scenario, then we can hopefully help narrow down the problem and get it resolved. Thanks.
