Problem summary

• ****************************************************************
  * USERS AFFECTED:  IBM WebSphere Application Server version    *
  *                  6.1 users with short virtual host aliases.  *
  ****************************************************************
  * PROBLEM DESCRIPTION: On systems with both *:port and         *
  *                      hostname:port virtual host aliases      *
  *                      defined, and the hostname is shorter    *
  *                      than 4 characters, some applications    *
  *                      fail to start.                          *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  During application startup, if the virtual host has both a *
  and a very short hostname alias, the webcontainer, after
  loading a first application which uses the virtual host
  aliases, will fail to load subsequent apps which use same the
  same aliases.  This will lead to error messages such as:
  Failed to load webapp: Context root /MyApp/* mapping unable to
  be bound.
  For example by default the default_host has an alias of
  *:9080. If a second alias is then added for try:9080, a first
  app loaded will bind to *:9080 and try:9080, but subsequent
  applications will be bound to * twice leading to the error.
  

Problem conclusion

• Modified code so that host alias are handled correctly.
  
  
  The fix for this APAR is currently targeted for inclusion in
  fixpack 6.1.0.19.  Please refer to the Recommended Updates
