I believe the EJB container is not being unregistered from the MBeanServer. In Branch_4_0 it worked like this: Registration: EjbModule.createService() --> MBeanServer.registerMBean() Unregistration: EjbModule.destroyService() --> ServiceController.remove() --> ServiceCreator.remove() --> MBeanServer.unregisterMBean() That seems like a pairing of actions that could easily get broken. In HEAD, the registration part is the same. Unregistration is: EjbModule.destroyService() --> ServiceController.remove() --> ServiceController.safelyRemoveAnyRegisteredContext() --> org.jboss.dependency.spi.Controller.uninstall() .... registerMBean call in EjbModule.createService() wasn't magically being reversed ;) Adding a server.unregisterMBean() call to EjbModule.destroyService() made the problem go away, but I suspect that's not the right solution.

I've looked at the test log and there is no indication of a problem with the earlier test. In Jaroslaw's first post before, the log of the undeploy is also clean.

The first time I run test "X" everything is fine, deploying jar, binding home interfaces and finally unbinding home interfaces (what's not true because there are still visible in the JMXConsole). When I run the test again I get the IAEE. The whole package org.jboss.test.cmp2.* (over 250 tests) would run without any errors (now over 230 errors), when unbinding would work correct. For example, many tests have to bind EJBTestRunner to jndi, but only the first test can do it successfully, the others can't because EJBTestRunner isn't properly unbound and a repeated bind cause the IAEE. I doesn't happen with JBoss4. ________________________________ From: jboss-development-bounces(a)lists.jboss.org on behalf of Ryan Campbell Sent: Mon 2006-08-14 13:42 To: JBoss.org development list Subject: RE: [JBoss-dev] InstanceAlreadyExistsException afterundeployandrepeated deploy in JBoss AS 5.0.0 Beta Jaroslaw, look for any test timeouts. As Adrian mentioned, it is some test failing to teardown and tests timing out are likely suspects. Debug them first. If you see no test timeouts, then the problem becomes harder. In that case, would it be realistic for JBossTestCase to assert that the number of deployments remain constant between each deploy and undeploy()? Could be a simple mechanism to flag bad tests. ________________________________ From: jboss-development-bounces(a)lists.jboss.org [mailto:jboss-development-bounces@lists.jboss.org] On Behalf Of Jaroslaw Kijanowski Sent: Saturday, August 12, 2006 10:58 AM To: jboss-development(a)lists.jboss.org Subject: [JBoss-dev] InstanceAlreadyExistsException afterundeploy andrepeated deploy in JBoss AS 5.0.0 Beta Hello, I've got the following issue with JBoss AS 5.0.0 Beta: After I run a test (in "one-test" mode, so no previous test caused an time out etc.), I see on the server console that the corresponding jar is undeploying and the home interfaces are unbinding.
