I will try the to use the debugger then, although I have never done
this so I was wondering if you could point me to a wiki or a document
that discusses this. I'm guessing you run with mvnDebug instead of mvn,
then attach jdb with jdb --attach 8000. However having tried this I try
to create breakpoints in the test classes and it doesn't break so not
quite sure where to go from there. Thanks a lot!
