Error description
After the application of UQ65118, deploying an application with
classloadermode set to 'application', a
java.lang.StackOverflowError will occur.
at com.ibm.ws390.rmi.corba.ClientDelegate.servant_preinvoke
(ClientDelegate.java(Compiled Code))
at com.ibm.ws390.wc.container._RemoteWebContainerHome_Stub.creat
e(_RemoteWebContainerHome_Stub.java(Compiled Code))
(above repeated several times)
Local fix
Deploy the application with something other than 'application'
for classloadermode, i.e.,
something other than classloadermode=2.
Please refer to 
PQ53684 for a description of classloader mode
settings.
Problem summary
****************************************************************
* USERS AFFECTED: Users of the WebSphere Application Server    *
*                 for z/OS and OS/390 Version 4.0.1 who run    *
*                 servers in the Application Visibility mode   *
*                 of the classloader, and have applied PTF     *
*                 UQ65118 for APAR 
PQ52493.                    *
****************************************************************
* PROBLEM DESCRIPTION: In classloader Application Visibility   *
*                      mode, Web Container initialization      *
*                      enters a loop which eventually fails    *
*                      with a StackOverflow exception.         *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
The RemoteWebContainer_resolved.ear supplied in PTF UQ65118 for
APAR 
PQ52493 contained EJB implementation classes in the ejb-jar
file RemoteWebContainer.jar within the ear file.  In classloader
Application Visibility mode this violates classloader
constraints. As a result, Web Container initialization entered a
loop during EJB create(), which then failed with StackOverflow.
This error does not occur in the Compatibility, Server or Module
classloader modes.
Problem conclusion
The RemoteWebContainer_resolved.ear has been re-built without
the EJB implementation classes in the RemoteWebContainer.jar
ejb-jar.

This change affects COMPID 5655A9800 R401 for z/OS and OS/390.
The code changes are stored in CMVC under defect 82083.
