Using -XX:-EnableValhalla works for the time being.
The purpose of the test was to validate the new private `Class.getClassAccessFlagsRaw` method.
It might have avoided the issue by not using the SUPER/IDENTITY bit in the test,
especially since that bit is computed in Valhalla and does not match the bits in the class file.
