get errors when redeploying mbean

[kant...@gmail.com]

Hi all,

I met a strange problem. I have deployed a mbean with @Service annotation on a jboss 4 cluster which has 3 nodes. @Service annotation means there is only one instance of the bean existing in the jboss server, so each node one mbean.

This mbean is using a distributed list from Hazelcast. So after deploying, I get some information like this:

2014-03-14 13:21:35,774 INFO  [com.hazelcast.cluster.ClusterService] [172.19.60.2]:5701 [dev] [3.2-RC2]

Members [3] {
        Member [172.19.60.2]:5701 this
        Member [172.19.60.3]:5701
        Member [172.19.60.52]:5701
}


However, when I undeploy the artifacts and redeploy them, it becomes 6 members.

Members [6] {
        Member [172.19.60.2]:5701 this
        Member [172.19.60.3]:5701
        Member [172.19.60.52]:5701
        Member [172.19.60.3]:5702
        Member [172.19.60.2]:5702
        Member [172.19.60.52]:5702
}

Actually, I expect 3 instead of 6. Obviously, the mbean container did not destroy the mbean when the artifact is undeployed. Is there any way I can clean up the duplicate objects?

Btw, afterwards, I get some error information:

2014-03-14 13:39:00,406 INFO  [com.hazelcast.partition.InternalPartitionService] [172.19.60.2]:5701 [dev] [3.2-RC2] Can't overwrite cause

Does anyone know how to solve the problem?
