Class SimpleLock

java.lang.Object

org.jboss.threads.SimpleLock

All Implemented Interfaces:

java.util.concurrent.locks.Lock

final class SimpleLock
extends java.lang.Object
implements java.util.concurrent.locks.Lock

A simple lock impl which does no deadlock detection, no fairness, no reentrancy protection, no error checking, and has basically no frills whatsoever. Non-public due to its highly experimental nature. This probably won't work; in fact the only reason I'm even trying this is because I'm an obsessive moron.
