Two nodes having consistent failures with :

• java/net/MulticastSocket/Test.java
• java/net/MulticastSocket/NoLoopbackPackets.java

Fixed on test-docker-ubuntu2404-ppc64le-2 : https://ci.adoptium.net/job/Grinder/17758/console

Re-enabled IPv6 in docker config.

Azure dynamic nodes needs more investigation, problem is likely due to network configuration on the dynamically provisioned node , then running via docker..
