JDK-8234076 bug fix candidate

The fix looks reasonable to me, basically, if the command argument format is not legal, it’s possible we won’t find the main class when doing argument file expansion, and the index is -1 which could cause crash on Windows platform for the wildcard processing.

I think we should add a test case for this, probably in test/jdk/tools/launcher/Arrrghs.java.

As I understand it, the argument validation is done in a later stage after calling JLI_Launch.
