While investigating other issues with hotswap tests I noticed
2 tests on the Problemlist that I think can be restored.

I have not been able to reproduce the failure with hs102t002.
It is marked in the ProblemList as related to JDK-8203350,
but that bug is about hs201t002. It is also marked as related
to JDK-8204506, which is concerned with test hs102t002, but
is specific to a graal failure and is already recorded in
ProblemList-graal.txt

I did run into some intermittent failures with hs204t001 and the
utility class ExecDriver. It appears that it took advantage of other tests
building the class file. A simple directive to build ExecDirver will bring it
in line with the other hotswap tests.
