New Revision: 1074725

URL: http://svn.apache.org/viewvc?rev=1074725&view=rev
Log:
fix for: https://issues.apache.org/jira/browse/AMQ-2929

Added test showing how a Text Message that was compressed can be received in a state where
the text is not compressed but the Message compressed flag indicates it is resulting in an
exception from getText() indicating an unknown compression type.
