How to handle exception in SpringBoot correctly, so the exception will not be bubbled up to server log?

Question

I have a RestController which throws custom exception, BoogyException is extended by RuntimeException.

RestController:

@RestController
public class Test {
    @GetMapping(path = "/test")    
    public ResponseEntity<String> myTest() {
       throws new BoogyException("I am a boog exception.");
    }
}

BoogyException:

public class BoogyException extends RunException {
    public BoogyException(Exception exception) {
      . ....
    }
}

My @ControllerAdvice class maps the BoogyException and return ResponseEntity.

@RestControllerAdvice
public class MotherExceptionHandler {

    @ExceptionHandler(value = { BoogyException.class})
    public ResponseEntity<MyJsonExcp> handleBoogyException(final Exception ex) {
           ....
    }
}

MyJsonExcp is simple POJO with Jackson annotations.

When my RestController throws BoogyException, I can see the JSON formatted response correctly. However, a RuntimeException is logged as debug level by SpringBoot in my WildFly server's log also.

It looks like SpringBoot is bubbling my custom exception as RuntimeException to the server log.

Is there way to stop it?

Note: SpringBoot v2.7.0

Does this answer your question? [Prevent stack trace logging for custom exception in Spring Boot application](https://stackoverflow.com/questions/31250598/prevent-stack-trace-logging-for-custom-exception-in-spring-boot-application) — Nikolai Shevchenko, Mar 10 '23 at 13:08
@NikolaiShevchenko, Thank you for the link. However, it did not work for me. — MFH, Mar 11 '23 at 14:03
Because I am using WildFly server (external) and WildFly logging subsystem, I configure the WildFly logging subsystem to mitigate the issue. — MFH, Mar 30 '23 at 22:33
