Q: 

Memory leak in Websphere 7 + EJB3, a lot of instances of ClassMapping

Hi, sorry for my english, I speak spanish. I recently migrate an application from ejb 2.x to ejb3 (approx. 300 entities), Im using WebSphere 7.0.0.9.

After 10 hours of work, the system crash with an OutOfMemoryError.

Analyzing the coredump, I see a lot of instance of the org.apache.openjpa.jdbc.meta.ClassMapping class (please see the attached a screenshot).

I believe that the culprit is the list of ValueListeners of the Value class, but I'm not sure, and I dont know how to fix this problem.

Thanks
