In one of our application benchmarks with JPA 2.5 + weblogic 12c there is a strange memory related issue. The heap memory keeps increasing with benchmark & eventually it runs out. Analyzing the heap dump of managed server indicates the size of oracle.j2ee.ws.server.jaxrs.dms.monitoring.DmsApplicationEventListener in the heap is close to ~99%. Most of the events in event listener are related to org.eclipse.persistence.internal.sessions.RepeatableWriteUnitOfWork.
There is no special config enabled for JPA or eclipselink. Has anyone faced the same issue. What other specific configuration need to be enabled so the DMS event is not generated or this issue is expected.
