        Description

        The test serviceability/tmtools/jstat/GcCauseTest02.java expects the old space utilisation to be > 70%, but in this case it was only 62%. Something could have happened in the VM to cause this change, but given that no GC related changes has been pushed lately I think it is more likely that this test is slightly unstable. Given that no changes has been made to the test or related parts of the VM I don't think this is an integration blocker.

        java.lang.RuntimeException: Old space utilization should be > 70.0%, actually OU / OC = 0.6249234
