[jboss-user] [Clustering/JBoss] - Deprecated DistributedState in Cluster API for JBossAS 5

I have code with DistributedState to update some data (my own metrics) for all members in cluster.

Now I see that DistributedState (seems DistributedState.DSListenerEx too) deprecated but I don't know how to replace my code.

Take a look..

HAPartition part = ...;

DistributedState distState = part.getDistributedStateService();
DistributedState.DSListenerEx listenerState = new DistributedState.DSListenerEx() {
             * {@inheritDoc}
            public void keyHasBeenRemoved(String category, Serializable key, Serializable value, boolean locally) {
                // No-op.

             * {@inheritDoc}
            public void valueHasChanged(String category, Serializable key, Serializable value, boolean locally) {
                // Some logic...


/* Register state listener. */
distState.registerDSListenerEx(CATEGORY, listenerState);

Every cluster node start thread with metrics update in loop
  distState.set(CATEGORY, locNode.getJBossId(), localNodeMetrics);

Do you have any ideas how to replicate metrics for all nodes?
I see that CacheManager added in JBoss AS 5
