Problem summary

Problem conclusion
CICS TS has been updated to use a Liberty JVM server that is based on WebSphere Liberty version 25.0.0.6. IBM is required to provide you with certain notices and other information regarding third party components, included by this APAR and obtained as part of IBM WebSphere Liberty 25.0.0.6. This information is available at: https://www.ibm.com/support/pages/node/7247838 Note, CICS 6.3 became generally available with Liberty 25.0.0.6. At 6.3 this APAR refreshes Liberty to include the fix for https://github.com/OpenLiberty/open-liberty/issues/32394 When enabling a new Liberty JVM server with feature cicsts:security-1.0 and no ltpa.keys file, you may now see a CWWKS0005E in messages.log reporting "No available UserRegistry service" and FFDCs are captured. In the FFDCs you will see: "com.ibm.websphere.security.WSSecurityException: getActiveUserRegistry failed due to an internal error: CWWKS0005E: A configuration exception has occurred. No available UserRegistry service." and "com.ibm.websphere.security.WSSecurityException: getUserRegistry for realm null failed due to an internal error: getActiveUserRegistry failed due to an internal error: CWWKS0005E: A configuration exception has occurred. No available UserRegistry service." This has no known impact on functionality and the ltpa.keys file will be created by Liberty. This issue is being actively worked on by the CICS and Liberty Development teams.
