Well, it's all a moot point now.  :-)

cjb> I knew someone would say that.  :-)  Yeah, that's "next" down the road, once this
round of upgrades is done.

The SA installed JRE 8u181 and TC 8.5.30, which fixed the problem.  Bypassed CM, testing,
approval process, etc. - but it works!  Still don't understand what went wrong.
