org.apache.wicket.request.handler.render.WebPageRenderer - The Buffered response should be handled by BufferedResponseRequestHandler
Obviously, it looks not a big deal but apache wicket libs too old, even QB 9.0.
The error what I mentioned(looks already fixed) - https://issues.apache.org/jira/browse/WICKET-3239
Apache wicket - https://wicket.apache.org/learn/
When I chcked the apache wicket libs version, it is 1.5.0 and the latest release version of 1.5.x is 1.5.16. (05 Aug 2016)
I just would ask you the plan regarding apache wicket libs update in QB.
Do you have it?
This problem should not affect usage of QB. Also QB uses stateful pages, so this issue may not solve the problem. We make a lot of customizations to wicket, we currently do not have plan to upgrade the lib.
