Bug 255903: java/openjdk14: Fix compile error (and possible segfaults) with
clang 12
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=255903
--- Description ---
During an exp-run for llvm 12 (see bug 255570), it turned out that at least
openjdk11 and openjdk12 do not build with clang 12.0.0. The exp-run therefore
skipped openjdk14.
Building this manually shows that it results in a compile error:
gmake[4]: Leaving directory
'/wrkdirs/share/dim/ports/java/openjdk14/work/jdk14u-jdk-14.0.2-12-1/make'

This is due to a missing backport of this commit [1]:

Even after applying this fix, there is still a possibility of a segfault during
the build, due to another missing backport, of this commit [2]:
commit c484d8904285652246c3af212a4211b9a8955149
