So, in order to preserve these test semantics, I'd rather think you should add the Exception type "java.nio.channels.UnsupportedAddressTypeException" to the catch clause in line 60. This should fix the test error in the failing cases, at least in our environments while still testing that no crashes occur everywhere.

I agree, it should be catching UnsupportedAddressTypeException. We 
should also update the test description to run the test twice, one with 
the default options, the second with -Djava.net.preferIPv4Stack=true.
