Bug 260319: java/openjdk11: various segfaults with llvm13
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=260319



--- Description ---
I'm seeing some segfaults on openjfx14 and other ports on -current amd64 and
aarch64 (it's the first failure I ever see on this port)

This affects openjdk8 and openjdk11.

I noticed that the patch in bug #258954 was removed, was it intentional? The
crash goes away if I compile openjdk with llvm12
