Handle or prevent duplicate invocation of lifecycle callbacks
-------------------------------------------------------------

                 Key: JBAS-4718
                 URL: http://jira.jboss.com/jira/browse/JBAS-4718
             Project: JBoss Application Server
          Issue Type: Task
      Security Level: Public (Everyone can see)
          Components: Clustering
    Affects Versions: JBossAS-5.0.0.Beta2
            Reporter: Brian Stansberry
         Assigned To: Brian Stansberry
             Fix For:  JBossAS-5.0.0.Beta3


The JMX interfaces for a number of clustering beans expose the old ServiceMBean lifecycle methods.  Effect of that is that the lifecycle methods get invoked twice -- once by the MC for the pojo service, and once by the ServiceController for the proxy created via the @JMX annotation on the bean.  This duplicate invocation leads to errors as shown in the forum.

Likely solution is to change the various services so they don't implement ServiceMBean.  Then change the name of the lifecycle methods to something the ServiceController doesn't recognize.  Annotate the methods so the microcontainer recognizes them.

Another solution is to have the services be aware of their current lifecycle state and ignore meaningless lifecycle callbacks.  The JBoss Cache JMX wrappers do that.
