Another change I'm making is regarding the buffer on JBossMessage. JBossMessage is caching the buffer when it is created, but receiving message in chunks is replacing the buffer when necessary. So, I have changed it to not cache the ByteBuffer any more, and aways get the buffer from the inner Message. There was a TODO about getting the buffer lazily, so I've made the change.
