    Description

      FULL PRODUCT VERSION :
      java version "1.5.0_01"
      Java (TM) 2 Runtime Environment, Standard Edition (build 1.5.0_01-b08)
      Java HotSpot(TM) Client VM (build 1.5.0_01-b08, mixed mode, sharing)

      ADDITIONAL OS VERSION INFORMATION :
      Microsoft Windows XP
      Professional
      Version 2002
      Service Pack 2

      A DESCRIPTION OF THE PROBLEM :
      Using IPv6 addresses in conjuction with NIO channels raises a "java.net.SocketException: Address family not supported by protocol
      family".

      Doing the same operation directly on a socket instance (i.e. without getting the socket from a channel) works.



      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Simply execute the piece of code below.

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      The program should run without exception (as it is the case for linux/solaris boxes on which it has been tested too).

      Should display:
      ==> 1
      ==> 2
      ==> 3

      ACTUAL -
      ==> 1
      ==> 2
      java.net.SocketException: Address family not supported by protocol
      family: bind
              at sun.nio.ch.Net.bind(Native Method)
              at
      sun.nio.ch.ServerSocketChannelImpl.bind(ServerSocketChannelI­mpl.java:119)
              at sun.nio.ch.ServerSocketAdaptor.bind(ServerSocketAdaptor.java­:59)
              at sun.nio.ch.ServerSocketAdaptor.bind(ServerSocketAdaptor.java­:52)
              at external.ipv6.main(ipv6.java:31)

      ERROR MESSAGES/STACK TRACES THAT OCCUR :
      Stacktrace is displayed by the application already.

      REPRODUCIBILITY :
      This bug can be reproduced always.
