This has something to do with the jetty web server and not ActiveMQ. I have the exact same issue with regular http and tried my best to work around the issue. There is no book or guide on Jetty and ActiveMQ so I could find an alterations in the xml files that worked. I tried quite a few that said they would alter the size of data that you post but nothing worked. My best suggestion is find a way to make your data smaller. If thats not an option, learn to be a Jetty expert and please post here or email me direct on how you got this done because I need it too.
