thanks!

the test will be reported by jtreg as passed w/ a "sub-status" skipped and the exception's message as detail; this substatus is recognized by our test execution system, and all skipped tests are reported separately from passed-passed.

as I explained in another RFR, this cleanup is a spin off from my other work, I didn't plan to convert all cases. I will file RFEs to expand this and other cleanups, I doubt thought that I will be able to work on them, yet I'll be happy to assist whoever decides to work on them.
