[jboss-user] [JBossCache] - Re: Problem in Optimistic Locking

[manik.surtani@jboss.com]

They both support concurrency; it's just that optimistic locking will allow readers to read while writers write, allowing a *higher level* of concurrency.

Regarding the deadlock with remote prepares, this is a possibility with both OL and PL, since remote locks are only acquired on prepare and not at the start of a transaction.  

Locks should be released after the transaction times out though; which forum thread are you referring to about this being reported as a bug?
