AdaptorMulticasting.java fails on MacOS/AArch64

[Andrew Haley]

test/jdk/java/nio/channels/DatagramChannel/AdaptorMulticasting.java fails with
a timeout because it asks for a password on the console. I guess this is some
sort of security thing on MacOS.

Maybe it'd work if I ran the test as root.

Is this expected? Should the test be excluded? Or is there something I can do
to make it work?

Thanks,
