Restarting a webapp via HTMLAdapter (jmx-console) works fine. Restarting a webapp via RMIAdapter, however, produces a lot of errors, mostly javax.management.InstanceAlreadyExistsException. Reading through the sources I could not find any serious differences between the way the HTMLAdapter invokes an operation on the MBean and the way RMIAdaptor does. The provided Ant task (jbossjmx-ant.jar) doesn't work either. Perhaps someone has a good hint or tip for me?
