      Description

        Even though JDK-8311306 resolved one source of this test failing with the "out of expected range" error message, we're seeing that it can still fail under -Xcomp on libgraal. It seems to happen when the ThreadCpuTimeArray::doit method is deoptimized at the "wrong" time and the time taken to recompile it increases the delay between 2 timing calls for the thread running that method. The delay can be increased beyond the threshold expected by the test, causing it to fail:

        java.lang.RuntimeException: TEST FAILED: MyThread-1 CPU time = 9189423 previous CPU time 8584379 out of expected range
