RFR: 8247463: [TESTBUG] java/nio/channels/etc/OpenAndConnect.java fails due to IPv6 not available

[Daniel Fuchs]

Hi Jie,

This sounds reasonable to me. However - I wonder if  a better way
to look at things would be to use IPSupport.hasIPv4() and
IPSupport.hasIPv6() - in conjunction with IA4LOCAL == null and
IA6LOCAL == null to decide what test case is appropriate to
run.

AFAIU, a machine may have no IPv6 local address configured (and
IA6LOCAL would be null), but might still have the IPv6 stack
and be able to use the IPv6 loopback.

So I'd prefer if a finer grained strategy was used to maximize the
number of tests that are performed on a given machine.

best regards,
