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
