PH44095: Fix SRVE8501E Error in Webcontainer

PH44095: Fix SRVE8501E error in web container on 22.0.0.2

APAR status

• Closed as program error.

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.

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:                                              *
  ****************************************************************
  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:
