Clustered @Singleton

Key: EJBTHREE-2234
URL:
https://issues.jboss.org/browse/EJBTHREE-2234
Project: EJB 3.0
Issue Type: Feature Request
Reporter: Carlo de Wolf
Labels: clustered
Fix For: TBD AS 7, TBD EAP 6
It should be possible to create a clustered singleton by just adding the @Clustered
annotation.
@Singleton
@Clustered
public class MyScheduler {
}
Care should be taken that the life-cycle callbacks are only invoked once on one node, the
other nodes will only receive the state of the singleton after post-construct.
Concurrency management of the singleton should happen cross-cluster, so that a singleton
with read lock can be concurrently invoked on any node. After existing a method with a
write lock the state must be synchronized across the cluster before new invocations are
processed.
