I thought it's nicer if the structure of the jar file to test could be defined in the code rather than by directory trees checked into mercurial. But if you think, it's not a good idea to refacture this, I can also leave it untouched. I could alternatively add my test as a net new testcase.

Thank you for the follow up.

No the restructure of the test and getting rid of the  directory tree and just building the jar within the test is good

I do not have a strong preference either way.    In the past, I have been suggested to clean up anything created.  I agree it can be handy if it these types of things remain after a failure

I think you are good to go.
