It was introduced by recent push of JDK-8219584, I linked the bug.

I see other tests that use SafepointAtLot without unlocking it, are those failing too?
 runtime/handshake/HandshakeTransitionTest.java

It has @requires debug, which probably unlocks the flag automatically.

Looks good and trivial to me.
