我想在jBoss里面用ZooKeeper做分布式锁，结合ehcache做缓存共享?报错

报错：

就是这一步的时候报错：

csAccessor.lock();//就是这一步的时候报错：
csAccessor.put(Long.valueOf("123"),new AlertSession());
boolean a = csAccessor.containsKey(Long.valueOf("456"));
boolean b = csAccessor.containsKey(Long.valueOf("123"));
csAccessor.unlock();

获取锁的方法：

public static Lock getZKLock(){
ZkSessionManager manager = new DefaultZkSessionManager(connectionString, timeout);
Lock lock = Locksmith.reentrantLock(manager, lockPath);
return lock;
}
