FWIW, I have indeed tried to backport the OpenJDK upstream fix for https://bugs.openjdk.org/browse/JDK-8229258 to older JDKs. But this is *ver= y* hairy and complicated, especially if you are not deeply invested into the J= DK sources. OpenJDK upstream has apparently also drawn the same conclusion, and did not officially backport the fix to OpenJDK 8, 9, 10, 11, 12 and 13. So I think = they just assume that you will compile an "old" JDK with a similarly "old" toolchain. (Note there is a pull request for OpenJDK 11 at https://github.com/openjdk/jdk11u/pull/23, but that was never merged into t= he official repository, as far as I can see. This was also mentioned in <https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D258954#c3>.) Having said all that, there may be another workaround except building with = an older toolchain, which is at <https://github.com/battleblow/jdk11u/commit/305a68a90c722aa7a7b75589e24d5b= 5d554c96c1>. This is applicable to JDK 11, but I guess it might also apply to JDK 8. I believe that JDK 9 through 13 already expired, so we can ignore those. Maybe somebody has the time to check that patch? --=20 You are receiving this mail because: You are the assignee for the bug.=
