Review request: JDK-8159596 Add java --dry-run

[Paul Benedict]

Mandy, if I am reading the diff correctly, it looks like you moved the
error exit code (1 = unhandled exception) inside the "else" block for a
real run only? I think if the dry run also throws an exception, you should
set the exit code to 1. If I read the diff wrong, my apologies :-)

Cheers,
Paul
