many WARN log messages on [struts2.dispatcher.mapper.DefaultActionMapper]

[oliverwi]

These are the two types of WARN log messages I get since I upgraded to 8.0.2

2023-01-16 20:46:27,968 WARN [http-nio-8090-exec-9] [struts2.dispatcher.mapper.DefaultActionMapper] cleanupActionName nice page did not match allowed action names [a-zA-Z0-9._!/\-]* - default action index will be used!
