EJB's node is dropped from the cluster if it is accessed during (re) start

Description of problem:
Under normal circumstances a restart of one node will signal to the client that it becomes unavailable and available.
But if the client-server try to invoke the EJB during the restart phase, it seem to be after the server-core (JGroups) is up but the application is not complete deployed, the client notice that the server is up but there is no application and it gets dropped from the list of the cluster forever.
