Neither the `send()` nor the `receive()` APIs of `DatagramSocket` specify that they throw this specific exception, but the test seems to catch it and consider it a socket timeout. So I'm guessing this test and the catch block was written with some specific context in mind and I didn't want to change that part as part of this PR which only aims to enable logging by default. Plus like Mark notes, the spec says `PortUnreachableException` "may" be thrown and isn't guaranteed.

as I indicated below, we have tracked and investigated this issue and it is not purely a macosx-aarch64 issue. It may also be a  test env issue. As such using the OS filtering in the test, which is designed to primarily exclued AIX, wouldn't be the appropraite approach. If we wish to exclude the test on macosx-aarch64, then use of Problemlist is more appropriate.
