[teststabilization] RFR: 8223856: Replace wildcard address with loopback or local host in tests - part 8

[Daniel Fuchs]

Hi,

Please find below a fix for [1]:
8223856: Replace wildcard address with loopback or local host in
          tests - part 8

http://cr.openjdk.java.net/~dfuchs/webrev_8223856/webrev.00/index.html

Some of the test failures weren't all attributable to the use
of the wildcard: in some cases tests make assumptions that
are not guaranteed to be true - e.g. given two different
interfaces `i1` and `i2` you may not assume that because you
can bind to i1 with port `p`, ephemerally allocated, you should
also be able to bind to `i2` with the same port `p`.

In such a case I have taken the liberty to add a retry mechanism,
(that is: try again the whole thing) in the hope
of decreasing the probability that someone else might
be again bound to the new ephemeral port on the other interface.

best regards,
