Gary Tully resolved AMQ-3497.
-----------------------------

    Resolution: Fixed

fix in http://svn.apache.org/viewvc?rev=1170523&view=rev

a subscription receipt is now delivered eagerly, it does not wait for the broker subscription response, such that it cannot be preceded by a message delivery.

> When a receipt[1] is specified on a subscribe frame, it is possible that a message dispatch on the newly created subscription gets delivered  before the RECEIPT, causing a stomp client to error out. The perl client  http://search.cpan.org/~lcons/Net-STOMP-Client-1.1/ gives
> {code}*** unexpected RECEIPT frame received: xxx {code}
