Subject Re: activemq-cpp problem connecting with openwire 5.4.0
Date Wed, 21 Apr 2010 15:07:15 GMT
I'm not aware of any changes in the trunk version that would affect the C++
client.  I've run our tests against 5.4 SNAPSHOTS without issue.  Could you
provide a test case that demonstrates the problem, its possible you have
found a bug in the C++ client.  If you are sending the message from a Java
client then please include that as well.

Just a note that there is no 5.4.0 release yet, only SNAPSHOT versions, so
that code is still in flux.
