So I do not stop/destroy/unload the MBeans needed for 8082 in a debug shutdown class I am about to commit for Your comments/solutions ... Right now i have a handle to all services from ServiceController.getDeployed() in org.jboss.system.Shutdown.shutdownServices() and are doing some logic there ... my findings *drive* towards separating the shutdown in *phases* and then perhaps delegate from from shutdownServices() to : Core (GPA) Core Services (MBeans) Deployments (AutoDeployer) I am not shure if the shutdown hook should be installed as a MBean ? ... maybe as a POJO in the main class ? ... eitherway We need to Map the (un)dependecy logic ? ... somehow ... The first undeployed should be the last -> first deployment (AutoDeployer) Then undeploy depending on dependencies (MBeans) The last undeployed should be the log Then System.exit(0) will take care of GPA There seem to be a fragmentation in how We behave in our MBeans with stop/destroy/unload and naming semantics...

As soon as the identity of the instance is established. This way the calls to business methods in ejbPostCreate() will get an already cached context via AbstractInstanceCache.get() and this method (AbstractInstanceCache.get()) will not blindly acquireContext(), set it's id, activate it and so on... only to later, when time has come to insert the created context, find out that some other context with same id has already been inserted... This is my ignorant understanding of the matter (I have just downloaded the sources and began to study the EJB specs a few days ago)...
