Project: ActiveMQ C++ Client
Issue Type: Bug
Components: Openwire
Affects Versions: 2.1
Reporter: Albert Strasheim
Assignee: Nathan Mittler
Attachments: owdurableunsub.patch
Calling unsubscribe on an Openwire session fails. The C++ application throws
the following exception:
response from futureResponse was invalid
FILE: ..\src\main\activemq\transport\filters\ResponseCorrelator.cpp,
LINE: 146
FILE: ..\src\main\activemq\transport\filters\ResponseCorrelator.cpp,

On a recent ActiveMQ 5.0-SNAPSHOT broker the following is printed in the
console:
Exception in thread "ActiveMQ Transport: tcp:///127.0.0.1:1900"

A patch for the Openwire durable subscribe integration test is attached to
perform an unsubscribe when everything is done. This reproduces the problem.
In a related matter, why is unsubscribe not supported for Stomp? Is it due to a
protocol limitation?
