java/bootstrap-openjdk8 broken?

I am trying to build openjdk8 on an aarch64 system, and have found that bootstrap-openjdk8 has problems downloading, and fails to run on this system.  This is probably related to https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=264065, but that pertains specifically to compiling java/openjdk8, not java/bootstrap-openjdk8.  I’ve included output from a build and run attempt below.  As you can see, there is a problem with the download, I’d guess with the DISTVERSION_aarch64 value, but maybe it’s distcache.FreeBSD.org that’s wrong.  Unfortunately, http://distcache.FreeBSD.org/local-distfiles is no-read, so I can’t look at what files are actually available.

In any case, it would be nice if someone could look into the download issue, and also see about get working version of bootstrap-openjdk8 for aarch64 available.

The system I’m running on is FreeBSD 13.1 on VMware Fusion on a Mac Mini M1, and I’m building in the 2022Q3 ports tree.
