Fix os::naked_short_nanosleep on OpenBSD when < 20 miliseconds. - #68
Merged
Conversation
nanosleep(2) on OpenBSD is currently accurate down to 20 miliseconds. Below 20 miliseconds, use a busy loop with SpinPause. This fixes serviceability/jvmti/vthread/ThreadStateTest/ThreadStateTest failure on OpenBSD.

It took a few tries to pass java/math/BigInteger/largeMemory/SymmetricRangeTests.java on OpenBSD in GHA. I believe that is unrelated to this change though. I ran that test 100 times on my hardware on both amd64 and aarch64 and it is not reproducible for me outside GHA. |
