TP$MyHandler.handleSingleMessage() makes an unnecessary copy of the buffer -------------------------------------------------------------------------- Key: JGRP-1773 URL: https://issues.jboss.org/browse/JGRP-1773 Project: JGroups Issue Type: Enhancement Reporter: Bela Ban Assignee: Bela Ban Fix For: 3.5 When a single message is received, we pass it to the thread pool for parsing, passing a copy of the byte array to the MyHandler runnable. The parsing then creates a new Message and calls readFrom(). This method reads the headers and then creates a payload buffer of the size read from the input stream, then copies {{size}} bytes from the input stream to the mesage's payload. This is an unneeded copy; as we already have a copy of the byte array, we only need to *reference* the byte array from the message and set the offset and length, saving us one copy of the buffer.
