8217427: [TESTBUG] nio/channels/DatagramChannel/UseDGWithIPv6.java fails without IPv6

[Langer, Christoph]

Hi Nick,

first of all, thanks for looking into this issue. We can see it on some of our test machines, too, so we are very interested in getting this fixed.

The test description says: "Check using IPv6 address does not crash the VM". 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.

Please also adjust the copyright year.

Thanks
Christoph
