---------------------------------------------------------------

In current version, the message passed to consumeMessage callback is an 
instance of MessageClientExt, which getMsgId has been overide to return uniq 
is, so if user calls MessageDecoder.decodeMessageId , they are decoding a 
uniqId instead of a true message id.


So , this problem is that, the user should not call this interfaces manually, 
though it is ok to call in an old version.
