Closed as program error.

Error description
In a Model clone environment, useing "stop" to stop an appserver
results some requests to be lost while the server is being stopp
 Using "Force Stop" does not result in new requests being lost
but the existing requests that are being processed may be lost
CU would like to use "Stop" to close all resources gracefully
without losing any new requests.

****************************************************************
* USERS AFFECTED: WebSphere Application Server with client     *
*                 applications.  Error 404 may be seen when    *
*                 the clone server is stopped.                 *
****************************************************************
* PROBLEM DESCRIPTION: Contained components within app server  *
*                      were being stopped before app server    *
*                      was stopped leaving a window open where *
*                      http requests could still come to app   *
*                      server but no underlying component to   *
*                      service them.                           *

* RECOMMENDATION:                                              *
****************************************************************
When clients (e.g., browsers) are being handled by multiple
clones and one of the clones is shutdown via "Stop", then some
client(s) may see a 404 (Not Found) response.  This condition
is transient, i.e., after a short period, no more 404 responses
are seen but this behavior is not consistent with seamless
failover.
Problem conclusion
A code error in ActiveEJBServer.java was corrected.
