      The following test failed in the JDK14 CI:

      vmTestbase/nsk/jvmti/unit/timers/JvmtiTest/TestDescription.java

      Here's a snippet from the log file:

      CURRENT: total time returned by "GetCurrentThreadCpuTime".
      OTHER: total time returned by "GetThreadCpuTime".
      EXPECT: the expected time if TestThread.run() had a proportional cost across all threads.
      % DIFF: how much "Expect" is off by.
