[ http://jira.jboss.com/jira/browse/JBCACHE-461?page=comments#action_12348254 ]
Bela Ban commented on JBCACHE-461:
----------------------------------
Lock upgrading is not supported by RRWL as discussed in
http://altair.cs.oswego.edu/mailman/private/concurrency-interest/2006-Nov....
The suggested solution is to subclass RRWL, which is actually done in JBossCache.
As an alternative, we could investigate using an AbstractQueuedSynchronizer, as suggested
in
http://altair.cs.oswego.edu/mailman/private/concurrency-interest/2006-Nov...
