Oh, interesting.  So the non-determinism problem still exists, and
java.base.jmod contains non-deterministic SHA-256 hashes.  But jlink
seems to no longer check whether the hashes match, so the jlink tests
now work.  This does seem to be to be a poor resolution to the
(Debian) bug!  No idea why they've done this, though.

So I suggest that we still use the patch with openjdk-15 to avoid
introducing non-determinism into the build, but this is clearly less
important than on 11 and 14.

Good question.  It's easy to do, and it does fix a bug, so I don't see
a good reason not to do so.

Indeed, but we can still fix it (and in the changelog say something
like "fixes bug #... for this version of openjdk").

Best wishes,
