Hi,

  test/java/net/Inet6Address/B6558853.java tests if the address obtained from getHostAddress() on connections
  using IPv6 link-local addresses contains the zone id. For Inet6Address.getHostAddress() to return the zone id,
  Inet6Address.scope_id_set needs to be set to true in addition to setting the appropriate Inet6Address.scope_id.
  In case of Windows XP/2003 with IPv6 enabled, the native socket implementation of socketAccept() method in
  src/windows/native/java/net/TwoStacksPlainSocketImpl.c does not set the scope_id_set to true which causes
  the zone id not to be returned, and B6558853 throws a RuntimeException.

The fix is to simply set the scopeidsetID in socketAccept() method to true if the scope_id is greater than 0.
