Error description

Local fix

• Remove the PropertyPermission from this file:
  
     WAS_USR_HOME/config/cells/CELL/nodes/NODE/app.policy
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: WebSphere Application Server users who use   *
  *                 ClassLoader resource loading with Java 2     *
  *                 security enabled and who have removed the    *
  *                 permission for reading system properties.    *
  ****************************************************************
  * PROBLEM DESCRIPTION: A security exception occurs while       *
  *                      initializing the class that implements  *
  *                      URLConnection.                          *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The subclass of URLConnection reads a system property when it
  is initialized. If the application does not have permission to
  read this system property, then a security exception will be
  thrown.
  

Problem conclusion

• The system property is now read earlier during server startup
  while the executing code has the system security context.
  
  The fix for this APAR is currently targeted for inclusion in
  fixpaks 5.1.1.14, 6.0.2.19, and 6.1.0.9.
