Thanks. Yeah, the problem here is the GHA is still using JTReg 6.1+3. The test passes for me locally too with 7+1 or 7+2, but fails as soon as I go back to 6.1+1.

Rather than altering the test significantly for this backport, let's see if we can update the JTreg used by 17u by backporting [8289798](https://bugs.openjdk.org/browse/JDK-8289798). It looks like the dependent changes to tests were already backported by @GoeLin so this might not be too risky.

Ah, I did wonder why the dependent fixes had been backported and not the update. I'll have a look at those PRs. It would be good to unblock this both for 11u & 17u.
