Summary: ActiveMethodOopsCache was used to keep track of old versions of
some methods that are cached in Universe but is buggy with permgen
removal and not needed anymore
There was a crash in this function that I couldn't reproduce. It was
likely that the crash was for something else, but this is a lurking bug.

Tested with vm.quick.testlist which includes redefine classes tests and
