jdk_net FAILED in Test_openjdk18_hs_extended.openjdk_aarch64_linux on test-docker* machines (aarch64)

Issues running some ipv6 tests on [test-docker-fedora35-armv8l-1](https://ci.adoptopenjdk.net/computer/test-docker-fedora35-armv8l-1) and other test-docker aarch64 linux machines. Note: Running jdk_net on test-equinix-ubuntu2004-armv8-0 (as shown in [Grinder/3857](https://ci.adoptopenjdk.net/job/Grinder/3857)) to see if ipv6 testcases can pass on that machine, which is not a test-docker* named machine.
