Chris Nauroth updated ZOOKEEPER-2227:
-------------------------------------
    Attachment: ZOOKEEPER-2227.001.patch

I'm attaching a patch.  Summary:
* Both the NIO and Netty connection classes now use a correctly sized buffer for reading the trace mask.
* {{FourLetterWordsTest}} has a new test to cover {{stmk}}.
* {{FourLetterWordsNettyTest}} is a new suite that subclasses {{FourLetterWordsTest}} but configures the Netty connection factory.  This will repeat all of the four-letter word tests through Netty.

> When the server handles the {{stmk}} four-letter word, it attempts to read an 8-byte Java {{long}} from the request as the trace mask argument.  The read fails, because the destination buffer's capacity is only 4 bytes.
