Thanks David, I missed that.

It says "testCurrentTimeMillis" and that is not monotonic. If the time-of-day clock got an adjustment at just the wrong time it could affect this test

The generated code looks OK to me. I wonder if this could be a problem with os::javaTimeNanos() on osx. This page says mach_absolute_time() is monotonic, but the implementation of javaTimeNanos() is treating it like it isn't: https://developer.apple.com/documentation/kernel/1462446-mach_absolute_time

ILW = test failure; intermittent on one platform; disable intrinsic = MLM = P4
