Unable to load configuration: /struts2-core-6.4.0.jar!/struts-beans.xml:39:72

With Struts 6.4.0 I get an error

18-04-2024 07:48:41.4 ERROR org.apache.struts2.dispatcher.Dispatcher - 
Dispatcher initialization failed

Unable to load configuration. - bean - jar:file: 
.../.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/SC/WEB-INF/lib/struts2-core-6.4.0.jar!/struts-beans.xml:39:72

This is probably related to the new caching mechanism. I added the new 
libraries from the standalone package at

https://dist.apache.org/repos/dist/dev/struts/6.4.0/

caffeine-2.9.3.jar (this is outdated with 3.1.8 being the latest)
checker-qual-3.1.9.0.jar (3.37.0 would be the latest)
error_prone_annotations-2.10.0.jar (2.26.1 would be the latest)

Did I miss something?

Thanks and best regards
