Hi I notice this ticket filed from a while ago - https://issues.apache.org/jira/browse/AMQ-7149. Currently if you wish to use the HTTP client, you need to make sure you have the stomp module on your classpath, as the http module references the XStreamSupport class.
I've attempted to pull the patch on the ticket into 2 PRs, 1 for master, and one for the 5.15.x branch. Is this a change the community could consider? I'd welcome and review and I'm happy to make any changes. Many thanks Jon
