Oops.

I discovered during the initial stages of that git bisect process that
3.8.0-rc4 is bad while 3.7.2 is good when using the latest git master
branch version of PLplot. That result surprised me (since I do recall
testing 3.8.0-rc4/ without issues), So my testing of 3.8.0-rc4 may not
have included java or some PLplot change between that test and now may
be affecting this good/bad result (although I think that is fairly
unlikely because I don't recall any specific java-related PLplot
changes during that period),

Anyhow, I am now bisecting between CMake 3.7.2 and 3.8.0-rc4 using a 
consistent PLplot version (the tip of our master branch) that is quite
well tested for CMake-3.7.2.  And if anyone here is attempting to
remember relevant language support changes, you should be thinking
about the period between 3.7.2 and 3.8.0-rc4.

More later on those git bisect results when that process is completed.
