[jdk18 arm32, aarch64] jdk_net failures related with IPv6

[sophia-guo]

Following jdk_net test failed on arm32 with jdk18, those tests suppose that IPv6 are supported on all platforms, which is not true for arm_linux.

java/net/InetAddress/HostsFileOrderingTest.java.HostsFileOrderingTest
java/net/InetAddress/InternalNameServiceTest.java.InternalNameServiceTest
java/net/InetAddress/InternalNameServiceWithHostsFileTest.java.InternalNameServiceWithHostsFileTest

For example java/net/InetAddress/HostsFileOrderingTest.java has testcases with -Djava.net.preferIPv4Stack=false -Djava.net.preferIPv6Addresses=true

or IPv6 tests is not conditional java/net/InetAddress/InternalNameServiceTest.java

and presumably with EXTRA_OPTIONS=-Djava.net.preferIPv4Stack=true they are still running and failing?

[sophia-guo]

Correct, EXTRA_OPTIONS=-Djava.net.preferIPv4Stack=true won't work with those tests. https://ci.adoptopenjdk.net/job/Grinder/4586/

[sophia-guo]

More tests with -Djava.net.preferIPv4Stack=true -Djava.net.preferIPv6Addresses=false

Same for jdk18 linux-aarch64 https://ci.adoptopenjdk.net/job/Test_openjdk18_hs_extended.openjdk_aarch64_linux/30/#showFailuresLink

TEST: jdk/net/ExtendedSocketOption/DontFragmentTest.java is also failing with IPv6 for JDK19 on xlinux

same for alpine-linux https://ci.adoptium.net/job/Test_openjdk20_hs_extended.openjdk_x86-64_alpine-linux_testList_2/23/#showFailuresLink

[sophia-guo]

Looks like this have been fixed in upstream https://bugs.openjdk.org/browse/JDK-8314517?jql=text%20~%20%22com%2Fsun%2Fnet%2Fhttpserver%2Fsimpleserver%2FCommandLinePositiveTest.java%22.

Tests were disabled since JDK18 and disabled forward to all newer versions. Grinders are not available for jdk 23,24 and works for jdk21. Fixes are in since jdk21. Make sense to enable for jdk21+.
