DistributedState service is a legacy component of the HAPartition service made available to HAPartition users via the
HAPartition.getDistributedState() method. This service provides coordinated management of arbitrary application state around the cluster. It is supported for backwards compatibility reasons, but new applications should not use it; they should use the much more sophisticated JBoss Cache instead.
In JBoss Enterprise Application Platform 5 the
DistributedState service actually delegates to an underlying JBoss Cache instance.
