Fix request (13u) -- will label after testing completed. I would like to backport the fix to jdk13u for parity with jdk11u. The original patch applied quite cleanly (slight merge was needed due to year changed in copyright).

Up the bug priority to P3. The bug affects all tests that uses realSync on OS X, approximate amount is 262 regression and 115 functional, not including implicit usage (subclasses etc).
