nathandeklepper opened a new issue, #2446:
URL: https://github.com/apache/activemq/issues/2446
Have tested this against 6.1.x where it works correctly.
On 6.3.x (and possibly 6.2.x) it fails with the exception pasted below.
Steps to reproduce...
Download activemq 6.3.1 tar.gz from amq classic downloads page.
Uncomment ws and stomp connectors in conf/activemq.xml
Connect with a ws/stomp client (should be reproducible with any protocol
over ws).

I have Java / spring test client that logs the following output, I'm not
sure how helpful this will be though as I expect the issue is dependency
version related on the server...
