@YaSuenag - I added the test to the ProblemList-zgc.txt file using:

    JDK-8268286 ProblemList serviceability/sa/TestJmapCore.java on linux-aarch64 with ZGC
    https://bugs.openjdk.java.net/browse/JDK-8268286

which is a subtask of:

    JDK-8268283 serviceability/sa/TestJmapCore.java failed with zgc on linux-aarch64 after JDK-8266957
    https://bugs.openjdk.java.net/browse/JDK-8268283

That leaves this bug (JDK-8268283) to pursue the problem report by @plummercj .

Please close this PR.
