Those tests also failed on build aix machine build-osuosl-aix71-ppc64-2 though with different error message.
https://ci.adoptopenjdk.net/job/Grinder/3282/
seven tests under java/net got error message like `Execution failed: `main' threw exception: java.net.NoRouteToHostException: A route to the remote host is not available.`
https://ci.adoptopenjdk.net/job/Grinder/3283/
three tests under sun/net got error message `java.net.BindException: The socket name is not available on this system. `

Review the linked CI failures and the ten named Java networking tests first, comparing the JDK 17 AIX and Grinder runs on the listed machines. Done means the root cause is identified and the affected tests no longer fail with the reported address or route errors.
