[10] RFR (XS): 8180366: [TESTBUG] gc/g1/humongousObjects/TestHumongousClassLoader should not be run with class unloading disabled

[Dmitry Fazunenko]

Hi Muthusamy,

To skip running a test if "-XX:-ClassUnloading" is given it's better to say:

@requires vm.opt.ClassUnloading != false

This will allow to keep the test running if no 'ClassUnloading' VM flag 
is specified.

Thanks,
Dima
