ASM ClassReader failed to parse class file - probably due to a new Java class file version that isn't supported

Question

I have created a war file, it is working fine as java project and tomcat 8.5, but when run that war file in tomcat 9, I faced following errors.

I have also update tomcat java version to 21 and update JAVA_HOME path as well added java bin location to Enviroment path but this issue is not getting resolved.

I am on Windows 11 operating system.

You need to upgrade version of Spring to at least 6.1.
