Sorry this comment is a bit late, but stack008 and stack0019 are passing
for me on an AArch64 system with 4k page size (the default for Ubuntu)
so it seems a shame to disable them unconditionally. I think PPC64 can
also be configured with 64k pages which would presumably have the same
problem.
Could we add a new jtreg property vm.pageSize and then make the
@requires line vm.pageSize == 4096 instead of os.arch != "aarch64"? I'm
happy to do that myself as this was pushed already.
