Hi Muthu -
There is a catch of course! 8-) There we are making it require the
explicit option -XX:+ClassUnloading, and would this make it skip the
test if that option isn't set, even though it might be the default
behaviour. I think we really want:
43 * @requires !(vm.opt.ClassUnloading == false)
..which jtreg understands, skipping the test if we explicitly disabled
ClassUnloading, running if we don't specify it, or if we explicity
The operators are mentioned here:
