Caught a very intermittent test failure in sh/jdk8 testing:

STDOUT:
Pauses expected = [1; 9223372036854775807], actual = 209
Cycles expected = [1; 9223372036854775807], actual = 209
STDERR:
java.lang.IllegalStateException: Cycle duration (209), pause duration (209)

But in STW mode, "cycle time" can equal "pause time". The test condition is not correct.
