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. Bug: http://bugs.sun.com/bugdatabase/viewbug.do?bugid=7183800 Webrev: http://cr.openjdk.java.net/~khazra/7183800/webrev.00/ 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.
