[jboss-user] [JBossCache] - Re: JBC 2 performance

I don't bother protecting/synchronizing the maps in a node when accessed via the XXDirect() calls as I assume that any locking happens on a higher level (see javadocs on NodeSPI). So clearly this higher-level sync wasn't working and hence the concurrent modification exceptions. And true enough, a bug in the PessimisticLockInterceptor was only acquiring read locks for remove(Fqn, Key) calls rather than write locks.
