Hi,
Some tests in our test repository assume that
InetAddress.getLocalHost() will return 127.0.0.1. However, with
linux systems running Ubuntu 12.04 now returning 127.0.1.1 as
localhost, these tests are failing. I have changed two
of the NIO tests to remove their dependency on
InetAddress.getLocalHost(). A third test has been added to
the ProblemList.txt since the changes required for it are more involved.

As Chris pointed out, these tests bind to the wildcard address and you
need a specific address to setup the address association, otherwise it's
highly platform/implementation specific as to whether it will do as
intended. So I think the proposed changes will cause problems where you
can't connect to 0.0.0.0 and so I think we need to look for another
solution.
Given that none of the TCP tests fail then it suggests it mean that
something else is going on, maybe something in the Ubuntu 12
configuration. Do these tests run if IPv6 is disabled? We've had issues
with some distributions where multicast tests fail and these have always
come down to iptables blocking IPv6 multicast packets causing the tests
to fail. I just wonder if we have something similar here.
