Problem summary

  • ****************************************************************
    * USERS AFFECTED:  IBM WebSphere Application Server V6.1 and   *
    *                  V7.0 users of JAX-RPC                       *
    ****************************************************************
    * PROBLEM DESCRIPTION: A StackOverflowError in                 *
    *                      LockableHashtable may occur when        *
    *                      a JAX-RPC web service is invoked        *
    ****************************************************************
    * RECOMMENDATION:  Install a fixpack containing this APAR.     *
    ****************************************************************
    When a JAX-RPC web service is invoked, a
    java.lang.StackOverflowError similar to the following may
    occur:
    
    java.lang.StackOverflowError
    at java.util.Hashtable.get(Hashtable.java:482)
    at
    com.ibm.ws.webservices.engine.utils.LockableHashtable.get(Lockab
    leHashtable.java:140)
    at
    com.ibm.ws.webservices.engine.utils.LockableHashtable.get(Lockab
    leHashtable.java:142)
    at
    ... there are a large number of repeated calls to the method
    ... LockableHashtable.get()
    at
    com.ibm.ws.webservices.engine.utils.LockableHashtable.get(Lockab
    leHashtable.java:142)
    at
    com.ibm.ws.webservices.engine.MessageContext.getProperty(Message
    Context.java:1337)
    at
    com.ibm.ws.webservices.engine.MessageContext.getPortName(Message
    Context.java:2180)
    
    This error may occur after the web service is called several
    times.
    

Problem conclusion

  • The StackOverflowError is due to an accumulation of
    LockableHashtable objects after multiple calls to the JAX-RPC
    web service.  The accumulation is due to a code path that
    inadvertently avoids a cleanup of these objects.  The code is
    changed to ensure that the cleanup occurs.
    
    APAR PK86465 has similar symptoms as this APAR.
    This APAR, PK96999, will fix both problems.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 6.0.2.41, 6.1.0.29 and 7.0.0.9.  Please refer to the
