    Summary: memory leak
       Type: Bug

     Status: Unassigned

Environment: Oracle 9i, WebLogic 8.1 SP1, JDK 1.4.2_01 (also on JDK 1.4.1_03)

Description:
Symptoms:
Deploy and undeploy the application about 10 times under WL 8.1 with -Xmx512m. I get OutOfMemoryException on the deploy.

I ran OptimizeIt Profiler over the app. server. It seems that Hibernate caches which contain instrumented classes are not released.

Application:
J2EE application, consisting of few SLSBs and uses Hibernate to access the database. Hibernate startup/shutdown is managed by WebLogic's ApplicationLifecycleListner. That's a listener which receives events on application startup and shutdown. I first thought that the issue was with the classloader. We used to initialize Hibernate inside WebLogic's classloader, but I get OutOfMemoryException even when using classloader of our application.
