I've pointed them at this thread. Hopefully I'll get more information
soon.

Right. I'd guess costs would be pretty minimal.

The main advantage for me personally is that I'd be able to fetch
runtime images supporting FreeBSD for use in jlink. My ultimate
intention is to put together a library/command-line tool/Maven plugin
that can automatically fetch JVM runtime images for a range of
architectures and operating systems and produce a jlinked application
image for every specified platform. "Build once, run on a selection of
platforms", sort of thing. The first part of this work is already done:

As you can probably imagine... None of the supported providers supplies
FreeBSD JVM runtime images. I could, with some hacking, grab the
FreeBSD binary packages and then unpack and reorganize the contents...
But it'd be a lot nicer if FreeBSD was a platform that worked just like
all of the others supported by AdoptOpenJDK and friends.

More people building and running the test suite can't hurt.
