  • java/net/MulticastSocket/Promiscuous.java
  • java/net/MulticastSocket/B6427403.java
  • java/net/MulticastSocket/NoLoopbackPackets.java
  • java/net/MulticastSocket/SetLoopbackMode.java

Tested java/net/MulticastSocket/Test.java on all Adopt aix machines, including test-osuosl-aix72-ppc64-1, test-ibm-aix71-ppc64-1, test-ibm-aix71-ppc64-2, and build-osuosl-aix71-ppc64-2. All grinders (https://ci.adoptopenjdk.net/view/Test_grinder/job/Grinder/7149 - 7152) failed with the same joinGroup failed error. So this failure is not likely to be machine related.

Tagging @aixtools as we may need assistance in determining whether we need to update machine configuration or exclude tests depending on what these tests are trying to do (failing with IPv6 socket cannot join IPv4 multicast group... have to check if this is the intent of the test).

My guess from the output "The socket name is not available on this system." is that the test may be expecting an IPv6 socket that is not present on the system, but I have not looked closely.

The only IPv6 address available, I expect, is ::1

Running the test - with save workspace - and I'll try adding some IPv6 interfaces (local only) - and see if that changes anything auto-magically.

As I do not know where to look in the java code...

does this question and answer offer any ideas? https://stackoverflow.com/questions/39111465/java-datagramchannel-multicast-defaults-to-ipv6

Another idea -

See: https://github.com/openhab/openhab-addons/commit/f3219acfba52c08a41b1dd8cd6a339d40eaef767 and search for private void handleRead(SelectionKey key) throws IOException {

  • FYI: with IPv6 addresses active - results are the same

For reference here are the links to the test code (for jdk16) which shows what each test is trying to do (also see the @run annotations at the top of the test for what commandline options are used):
