maoling commented on ZOOKEEPER-2857:
------------------------------------

Initialized may be a flag that distinguishes a real client connection from a cmd fourletter
.the main logic is in NIOServerCnxn#doIO and I debug it using org.apache.zookeeper.server.quorum.WatchLeakTest#testWatchesLeak.can
you give more your description?

> NIOServerCnxn.java
> private boolean readLength(SelectionKey k) throws IOException 
> if (!initialized && checkFourLetterWord(sk, len)) {

> I think this is a problem. when initialized is true, it also need execute checkFourLetterWord,
but it don't execute.
