JFR view: the "Park Until" field of jdk.ThreadPark is invalid if the parking method is not absolute

UNSAFE.park(true, System.currentTimeMillis() + 1000);
UNSAFE.park(false, 2000L * 1000 * 1000);

If the parking method is not absolute, the real value of "until" in JFR event is Long.MIN_VALUE, which will be convert back to java.time.Instant.MIN, but JFR view displays this value as '08:05:43' of my timezone.

This is somewhat misleading, better to show N/A.
