jdk_net_0, jdk_net_1 failures in AIX

**Describe the bug**
The (weekly) run of https://ci.adoptopenjdk.net/job/Test_openjdk11_j9_extended.openjdk_ppc64_aix/ is not finishing green. Examination of the last week shows in: https://ci.adoptopenjdk.net/job/Test_openjdk11_j9_extended.openjdk_ppc64_aix/34/ one build artifact and three Generated items: https://ci.adoptopenjdk.net/job/Test_openjdk11_j9_extended.openjdk_ppc64_aix_testList_0/, https://ci.adoptopenjdk.net/job/Test_openjdk11_j9_extended.openjdk_ppc64_aix_testList_1/, and https://ci.adoptopenjdk.net/job/Test_openjdk11_j9_extended.openjdk_ppc64_aix_testList_2/.

The first artifact finishes green,

**To Reproduce**
Steps to reproduce the behavior (or Grinder rerun link):

* 07:02:41.673 For example, to rebuild the failed tests in =https://ci.adoptopenjdk.net/job/Grinder, use the following links:
07:02:41.673 https://ci.adoptopenjdk.net/job/Grinder/parambuild/?JDK_VERSION=11&JDK_IMPL=openj9&JDK_VENDOR=eclipse&BUILD_LIST=openjdk&PLATFORM=ppc64_aix&TARGET=jdk_net_1

* 07:15:17.600 For example, to rebuild the failed tests in =https://ci.adoptopenjdk.net/job/Grinder, use the following links:
07:15:17.600 https://ci.adoptopenjdk.net/job/Grinder/parambuild/?JDK_VERSION=11&JDK_IMPL=openj9&JDK_VENDOR=eclipse&BUILD_LIST=openjdk&PLATFORM=ppc64_aix&TARGET=jdk_net_0

**Expected behavior**
A clear and concise description of what you expected to happen.

**Additional context**

* I am new here (aqa-tests) - be gentile :)

Start with a Grinder rerun for jdk_net_0 or jdk_net_1 and inspect test/jdk/java/net/MulticastSocket/Promiscuous.java, especially the failures at receive() line 77 and test() line 138. Compare the AIX output for the multicast datagram timeout; done means the affected AIX test-list jobs complete successfully.
