  * PROBLEM DESCRIPTION: NullPointerException fails              *
  *                      WASPostUpgrade in ServerIndexConfig     *
  *                      or InetAddressManager                   *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The problem is caused by an InetAddress object being null
  after the call to resolve a hostname string, because the
  hostname is not resolvable from the machine running
  WASPostUpgrade. Migration does not check for the null case, so
  a NullPointerException occurs.
  This problem occurs in different locations in the code
  depending on version. In 8.5.5, it will occur in
  ServerIndexConfig in setHostName(). In 9.0, it will occur in
  InetAddressManager in getInstance().
  This can occur if the user is performing a remote migration
  and the target profile is on a system that is isolated from
  the source system it was on. It can also occur on 9.0 during
  local migrations if there are old hosts in the virtualhosts.xml
  file that cannot be resolved.
  

Problem conclusion

• WASPostUpgrade was adjusted to handle the cases where
  InetAddresses are not found and not fail the migration.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.5.5.14 and 9.0.0.8.  Please refer to the Recommended
