RFR: 8285671: java/nio/channels/etc/PrintSupportedOptions.java and java/nio/channels/DatagramChannel/AfterDisconnect.java are failing

[Michael McMahon]

Hi,

Can I get the following fix reviewed please? JDK-8284890 was pushed yesterday and is causing failures on older versions of macOS that do not support the option. The fix here is to check at initialization time whether it is supported before adding it to the list of supported options. The error causes the new test and two existing ones to fail. I will remove the two tests from the problem list separately.

Thanks,
Michael.
