Steps to Reproduce
N/A

Expected behavior
The web application should start without the CWWKZ0002E error caused by the NPE.

Diagnostic information:

• OpenLiberty Version: [e.g. 21.0.0.8 - 21.0.0.10]
• Affected feature(s) mpJwt-1.2 and mpJwt-2.0
• Java Version: [i.e. full output of java -version]
• server.xml configuration (WITHOUT sensitive information like passwords)
• If it would be useful, upload the messages.log file found in $WLP_OUTPUT_DIR/messages.log
