ExceptionHandler in controller is not used by another controller

[uc4w6c]

Describe the bug
In the following cases, each controller should only return the HTTP Status set in its own ExceptionHandler.
An ExceptionHandler in a controller returns BAD_REQUEST.
An ExceptionHandler in another controller returns INTERNAL_SERVER_ERROR.
