    Description

      We see two compiler/rtm/locking tests failing regularly on ppc64le in JDK11.

      1. The test compiler/rtm/locking/TestRTMSpinLoopCount.java fails like this:
      java.lang.RuntimeException: Total aborts count (1002) should be less or equal to 1001: expected that 1002 <= 1001

      2. The test compiler/rtm/locking/TestRTMAbortThreshold.java fails like this:
      java.lang.RuntimeException: Expected that method with rtm lock elision was deoptimized after 1 lock attempts: expected 2 to equal 1
