Analyze Unclosed Sessions in Oak (1.0.13)

[#1]

Is there a session analyzer tool for Oak? The one referenced in this article [1] only seems to work for CRX in lower version.

Looking at a recent heap dump, we seem to have trouble with sessions not closing properly and are trying to narrow down where it's coming from.

Hi Jörg, is this the sort of warning you are talking about?

*WARN* [ip [1432319636774] GET something HTTP/1.1] org.apache.jackrabbit.oak.jcr.session.RefreshStrategy This session has been idle for 2 minutes and might be out of date. Consider using a fresh session or explicitly refresh the session.

If so, how would I go from this to finding out where this session is opened? The "session_analyzer.jar" from the article referenced above [1] seems to do just that. However, when run on an Oak repo, it doesn't seem to return anything (output.txt has 0 bytes). 

Sham, where in JMX would I see this sort of session information?
