Looks much better now, thanks for splitting the line into three calls.

Can the hard-coded `/home/runner/work/jtreg/jtreg` path be replaced with some inline `pwd` evaluation? Would make it more future-proof if parent paths are changed.

.github/workflows/test.yml line 74:

I assume that the hard-coded `/usr/local/openjdk21` is well-defined and stable for `pkg ... openjdk21 ...` calls. Or is there an environment variable (`JAVA_HOME`?) being set that can be read out and used here?
