 Replying to [comment:17 breun]:
 > MacPorts uses `-f`, but `/usr/libexec/java_home -h` only shows
 `-F`/`--failfast` (at least on 10.15). On which versions of macOS does
 `/usr/libexec/java_home -h` list `-f` as a valid option?

 It appears that we've been using `-f` since my commit here in October
 2018:
 https://github.com/macports/macports-
 ports/commit/4c0d76dc7a6bf8a319e3c23248abb15445f6dc16

 My OS X 10.8 VM also shows only `-F`/`--failfast`. I couldn't confirm 100%
 that `-f` and `-F` behave the same way because I don't have a JVM on the
 VM and it looks like a pain to get now (that Safari is too old for modern
 TLS, I guess).

 We could change it to `-F` but that's clearly not the cause of this
 particular problem.
