Error description

  • For WebSphere Application Server Liberty, in some instances
    there is an AccessControlException issued for a permission
    that had been granted in the application's permissions.xml
    file.  For example, for the following
    AccessControlException,
    
    java.security.AccessControlException: Access denied
    ("javax.security.auth.AuthPermission"
    "wssecurity.getRunAsSubject")
    	at
    java.security.AccessController.throwACE(AccessController.jav
    a:125)
    	at
    java.security.AccessController.checkPermission(AccessControl
    ler.java:198)
    	at
    java.lang.SecurityManager.checkPermission(SecurityManager.ja
    va:563)
    	at
    com.ibm.websphere.security.auth.WSSubject.getRunAsSubject(WS
    Subject.java:397)
    	at web.RunAsServlet.performTask(RunAsServlet.java:39)
    	at web.BaseServlet.handleRequest(BaseServlet.java:79)
    	at web.BaseServlet.doGet(BaseServlet.java:49)
    	at
    javax.servlet.http.HttpServlet.service(HttpServlet.java:575)
    	at web.BaseServlet.service(BaseServlet.java:43)
    	at
    javax.servlet.http.HttpServlet.service(HttpServlet.java:668)
    
    the permission javax.security.auth.AuthPermission was
    already defined in the permissions.xml file, but the
    exception was still issued.

    ****************************************************************
    For WebSphere Application Server Liberty, in some instances
    there is an AccessControlException issued for a permission that
    had been granted in the application's permissions.xml file.  For
    example, for the following AccessControlException,
    
    java.security.AccessControlException: Access denied
    ("javax.security.auth.AuthPermission"
    "wssecurity.getRunAsSubject")
    	at
    java.security.AccessController.throwACE(AccessController.java:12
    5)
    	at
    java.security.AccessController.checkPermission(AccessController.
    java:198)
    	at
    java.lang.SecurityManager.checkPermission(SecurityManager.java:5
    63)
    	at
    com.ibm.websphere.security.auth.WSSubject.getRunAsSubject(WSSubj
    ect.java:397)
    	at web.RunAsServlet.performTask(RunAsServlet.java:39)
    	at web.BaseServlet.handleRequest(BaseServlet.java:79)
    	at web.BaseServlet.doGet(BaseServlet.java:49)
    	at
    javax.servlet.http.HttpServlet.service(HttpServlet.java:575)
    	at web.BaseServlet.service(BaseServlet.java:43)
    	at
    javax.servlet.http.HttpServlet.service(HttpServlet.java:668)
    
    the permission javax.security.auth.AuthPermission was already
    defined in the permissions.xml file, but the exception was still
    issued.
    

Problem conclusion

  • The code was modified to prevent an AccessControlException from
    being issued when it was already granted to the application.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 17.0.0.1.  Please refer to the Recommended Updates page for
