SpringBoot [SpringBoot 3.2.0] Every 404 Exception Error Will Be Route To 500 in @ControllerAdvice

Problem :

After updating to SpringBoot 3.2.0 everytime 404 NoResourceFoundException happened, it will re-route to 500 error due to default exception handler in @ControllerAdvice.

   @ExceptionHandler
    @ResponseStatus(INTERNAL_SERVER_ERROR)
    fun handleAllOtherExceptions(ex: Exception) {
        log.error(ex) { "exception occurred" }
    }

How to reproduce :

Clone example project on my Github
Go to deployment/local and run sh start.sh (it will start docker container locally)
Run SpringBoot application
Test using Postman with invalid url :localhost:8100/invalidURI/1
To simulate success case, remove exception handler code bellow in class RestExceptionHandler:

   @ExceptionHandler
    @ResponseStatus(INTERNAL_SERVER_ERROR)
    fun handleAllOtherExceptions(ex: Exception) {
        log.error(ex) { "exception occurred" }
    }

Expected behaviour

404 NoResourceFoundException should not route to 500 error.
