Abstract:  Fix SRVE8501E Error in Webcontainer

Description/symptom of problem:  
PH44095 resolves the following problem:

ERROR DESCRIPTION:
The server may encounter SRVE8501E: The servlet container       
did not load with an acceptable version error for some          
features. The issue is most likely to occur with collective     
features such as collectiveController-1.0 and                   
collectiveMember-1.0. This error can also happen with any       
feature that relies on the two mentioned.                       
The servlet container keeps an internal record of which         
feature version is loaded, such as 3.1 or 4.0. The servlet      
code may misbehave if this error occurs since the internal      
version defaults to version 30.                                 

LOCAL FIX:

PROBLEM SUMMARY:

USERS AFFECTED:
 Users of Webcontainer on Liberty version
22.0.0.2 that use collective features.

PROBLEM DESCRIPTION:
Fix SRVE8501E Error for Servlet
Features

RECOMMENDATION:
None

When the collective related features (i.e collectiveController-
1.0, collectiveMember-1.0, or any others that require these
collective features) are enabled, the server exception
"SRVE8501E: The servlet container did not load with an
acceptable version" might occur. Due to this error, the server
uses the default 3.0 servlet version. The application might
therefore misbehave due to the incorrect version.

PROBLEM CONCLUSION:
The webcontainer code  in Liberty has been updated to avoid this
error.  The github link can be found here:

The fix for this APAR is currently targeted for inclusion in    
fixpack 22.0.0.3
