AdaptorMulticasting.java fails on MacOS/AArch64

[Jaikiran Pai]

Hello Andrew,

Is it the test that's asking for the password or is it the jtreg failure 
handler (which runs a bunch of post-failure commands for data 
collection) that's asking for the password? One of the post-failure 
commands is the "sudo dmesg" command of macos which requires the 
password. So, I suspect that's the one which is prompting for the 
password, *after* the test has already failed with some different reason.

If that's the case, then this relates to 
https://bugs.openjdk.org/browse/JDK-8286744. I believe, setting up the 
/etc/sudoers.d/sudoers file on your system for the /sbin/dmesg command 
should get you past this. I suspect, this needs to be documented in the 
build/testing documentation (or we need to somehow skip this command) - 
I'll raise a JBS issue for this.
