jdk_management_0 tests pass only on test-alibaba-ubuntu1804-armv8-1

[Haroon-Khel]

jdk_management_0 tests from the jdk11 hotspot extended openjdk suite seem to pass only on test-alibaba-ubuntu1804-armv8-1, https://ci.adoptopenjdk.net/view/Test_grinder/job/Grinder/1774/console

It fails on other aarch64 machines, such as test-docker-fedora33-armv8l-2

Hmmm could that be related to running in a docker containers? It isn't one that had been reported in adoptium/aqa-tests#2138. Does the same problem occur with the test on Linux/x64 in on test-docker systems?

yes, this is a known issue for docker specific. https://bugs.openjdk.java.net/browse/JDK-8255263
