> The method isChildReadLock in class ZKInterProcessLockBase may be wrong,
> which determines whether the lock is readLock or not. So we should compare
> the node name with READ_LOCK_CHILD_NODE_PREFIX rather than
> WRITE_LOCK_CHILD_NODE_PREFIX. Since there is no other method to invoke the
> method "isChildReadLock" now, we have not encountered an error.
> {code}
> protected static boolean isChildReadLock(String child) {
> int idx = child.lastIndexOf(ZKUtil.ZNODE_PATH_SEPARATOR);
> String suffix = child.substring(idx + 1);
> return suffix.startsWith(WRITE_LOCK_CHILD_NODE_PREFIX);
> }
> {code}
