Start with runtime/os/AvailableProcessors.java and reproduce the issue using the linked Grinder configuration for JDK 8 on arm_linux. Compare the test behavior across the available arm Linux nodes and identify why it only works on one node. Done means the testcase runs successfully on the intended arm Linux nodes.
