    Description

      FULL PRODUCT VERSION :
      java version "1.7.0-ea"
      Java(TM) SE Runtime Environment (build 1.7.0-ea-b59)
      Java HotSpot(TM) Client VM (build 16.0-b03, mixed mode, sharing)

      &
      Java(TM) SE Runtime Environment (build 1.6.0_11-b03)
      Java HotSpot(TM) Client VM (build 11.0-b16, mixed mode, sharing)

      ADDITIONAL OS VERSION INFORMATION :
      System:
      Microsoft Windows XP
      Professional
      Version 2002
      Service Pack 3

      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 -
      ==> 1
      ==> 2
      ==> 3

      ACTUAL -
      ==> 1
      ==> 2

      REPRODUCIBILITY :
      This bug can be reproduced always.
