> Key: AMQ-3703
> URL: https://issues.apache.org/jira/browse/AMQ-3703
> Project: ActiveMQ
> Issue Type: Improvement
> Components: Broker
> Affects Versions: 5.5.1
> Reporter: Timothy Bish
> Assignee: Timothy Bish
> Priority: Trivial
> Fix For: 5.6.0
>
>
> The Topic class uses an old AMQ class Valve that is essentially a pre JDK 1.5
> Read / Write lock. The JDK RW lock is much more efficient than ours using
> only a single CAS operation in many cases when multiple readers need access
> to the lock as opposed to the Valve class that requires all threads to
> synchronize and possibly wait on a monitor.
