> I'm seeing Java lock object contention in the org.jboss.invocation.pooled.interfaces.PooledInvokerProxy.getPooledConnection().  I would like to reduce the time that we hold the lock to boost performance.  In a load test, we were seeing contention up to 1-2 seconds waiting to get a connection from the pool.
> Proposed change to 4.x is attached.
