jtreg has been updated via CODETOOLS-7902003  to use a unique
test.classes directory. This is part of improving the reliability when
running tests concurrently. The change exposes issues in a tiny number
of tests that use test.classes in odd ways. For the jdk repo then two
tests need to be updated. There are a few others in the hotspot  and
langtools  repos that also need to be fixed before the jtreg
requiredVersion can be bumped to use a promoted jtreg with the change.
While in the area, I also changed a number of recent tests to not use
the temporary file system. Tim Bell has created a lot of bugs on this
recently, I think because he observed /tmp filling up.
The (trivial) patch with the updates to the tests is here:
I'd like to get this into jdk10/jdk10 to meet up with the test updates
in the other repos.
