Description

        public boolean execute() throws KeeperException, InterruptedException {
            do {
                if (id == null) {
                    long sessionId = zookeeper.getSessionId();
                    String prefix = "x-" + sessionId + "-";
                    // lets try look up the current ID if we failed 
                    // in the middle of creating the znode
                    findPrefixInChildren(prefix, zookeeper, dir);
                    idName = new ZNodeName(id);
                }

ZNodeName will throw an NPE if id is null.
