Yes, that fixes the java related errors, thanks! The test output now:

Ran 1243 tests, 1214 results as expected, 14 unexpected, 15 skipped (2024-11-10 21:57:05+0900, 86.333090 sec)

The remaining unexpected fails are mostly maxima tests.

I do have some version of maxima installed, but never use it, so no idea if it is integrated into emacs (and (featurep 'ob-maxima) returns nil).

I copy the output here in case useful:
