Spring Boot 4 - Redis Session Management Not Working

I migrated my Spring Boot version from 3.5.0 to 4.0.2. Previously, in 3.5.0 Redis session management was working fine.

Now, in version 4.0.2, after a lot of trial and error, I found that when @EnableRedisHttpSession is explicitly specified, it works properly. I have searched the Spring Boot repo and documentation, but I couldn't find any mention about this change.

Any help in understanding this would be appreciated. Thanks!
