Memory leak when reading EJB 2.1 CMP EntityBeans ------------------------------------------------ Key: AS7-4675 URL: https://issues.jboss.org/browse/AS7-4675 Project: Application Server 7 Issue Type: Bug Components: EJB Affects Versions: 7.1.1.Final Environment: Windows 7 Pro SP1 (64bit); JDK 1.6.0_31 (64bit); Oracle Database 11g Release 11.1.0.6.0 - 64bit Production; AS71.1Final / AS71.2 latest build Reporter: Klaus Benary Assignee: Stuart Douglas Priority: Critical Fix For: 7.1.2.Final (EAP) Attachments: HeapDumpScreenShot.png, JCTest-maven.zip, JCTest.zip After reading 12000 EJB 2.1 EntityBeans in a test application there are about 5 million Interceptor[] arrays firmely bound in the heap. A heap dump shows this as a typical reference chain: GC Root: ServiceContainerImpl$ServiceThread ServiceContainerImpl$ServiceThread.container = ServiceContainerImpl ServiceContainerImpl.registry = UnlockedReadHashMap UnlockedReadHashMap.table = AtomicReferenceArray AtomicReferenceArray.array = Object[16384] Object[6209] = UnlockedReadHashMap$Item[3] UnlockedReadHashMap$Item[1] = UnlockedReadHashMap$Item UnlockedReadHashMap$Item.value = ServiceRegistrationImpl ServiceRegistrationImpl.instance = ServiceControllerImpl ServiceControllerImpl.serviceValue = ImmediateValue ImmediateValue.value = TimedObjectInvokerImpl TimedObjectInvokerImpl.timeoutInterceptors = HashMap HashMap.table = HashMap$Entry[128] HashMap$Entry[123] = HashMap$Entry HashMap$Entry.value = ChainedInterceptor ChainedInterceptor.interceptors = Arrays$ArrayList Arrays$ArrayList.a = Interceptor[6] The number of bound objects keeps growing when reading more EntityBeans - even wehn reading the same beans again. Even after undeploy of the application the
