Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: The jcicsxClient-1.0 and                *
  *                      jcicsxServer-1.0 Liberty features will  *
  *                      not install in a Liberty JVM server     *
  *                      with the servlet-5.0 (Jakarta EE9) or   *
  *                      higher feature installed.               *
  ****************************************************************
  When enabling a Liberty JVM server with the jcicsxServer-1.0
  feature installed in CICS, or when starting a local Liberty
  server with the jcicsxClient-1.0 feature installed whilst also
  using the servlet-5.0 (Jakarta EE9) feature, the Liberty server
  will fail to enable the jcicsxServer-1.0 or jcicsxClient-1.0
  feature with the following message:
  
  CWWKF0033E: The singleton features servlet-5.0 and servlet-3.1
  cannot be loaded at the same time.  The configured features
  servlet-5.0 and cicsts:jcicsxServer-1.0 include one or more
  features that cause the conflict. Your configuration is not
  supported; update server.xml to remove incompatible features.
  

Problem conclusion

• CICS has been updated so that the jcicsxServer-1.0 feature will
  install with servlet-5.0 (Jakarta EE 9) or servlet-6.0 (Jakarta
  EE 10) features.
  
  There is a new jcicsxClient-2.0 feature available from the
  Liberty Repository.  This is compatible with Jakarta EE 9 and
  Jakarta EE 10.
  
  To use the new jcicsxClient-2.0 feature you need the fix for the
  following issue:
  https://github.com/OpenLiberty/open-liberty/issues/31741
  
  This is part of fixpack 25.0.0.7.
  
  When using the jcicsxClient-2.0 feature locally, a warning
  message with text "CDI container not available" may be written
  to messages.log.  This message does not affect the functionality
  of JCICSX and can be ignored.  This is being investigated in
  https://github.com/OpenLiberty/open-liberty/issues/32897
