There is a community contribution to the Tomcat plugin:
I created a branch off of master yesterday and put the patch in it:
In order to be merged into master and get into the next RHQ release, we need someone to
peer review this and test this. Is anyone available?
We do not have any unit tests, but I was asked to get some. I'll ask the submitter to
see if a unit test(s) is possible (this might be one of those that is hard to test today
because it will probably require integration tests with a running Tomcat instance).
