[teststabilization] RFR: 8224761: Replace wildcard address with loopback or local host in tests - part 12

[Daniel Fuchs]

Hi,

Please find a patch that fixes a batch of tests that have been
observed to fail intermittently. Usual symptoms, usual probable
cause, and usual recipe:

8224761: Replace wildcard address with loopback or local host in
          tests - part 12
https://bugs.openjdk.java.net/browse/JDK-8224761

webrev:
http://cr.openjdk.java.net/~dfuchs/webrev_8224761/webrev.00/

Note: I also took the opportunity to add a doPriveleged in the
NetworkConfiguration library class. If the code in question
doesn't have the appropriate permissions it prints truncated
info, which makes it otherwise unhelpful in tests that define
a security manager on the command line.

best regards,
