Wrong media type in #ExceptionHandler - spring-boot

Question

I have a rest controller with an endpoint for a download.
The endpoint can download a resource/entity, if it doesn't exist an error will be thrown.
The endpoint produces
application/octet-stream --> download
application/json --> error
Example
#RestController
public class ResourceController {
#GetMapping( value = "/{id}", produces = { "application/json", "application/octet-stream" } )
public ResponseEntity<Resource> download( #PathVariable final int id ) {
if ( id % 2 == 0 ) {
throw new EntityNotFoundException();
}
return ResponseEntity.ok( new ClassPathResource( "application.properties" ) );
}
}
The ExceptionHandler
#ControllerAdvice
public class ResponseExceptionHandler {
#ExceptionHandler( EntityNotFoundException.class )
public ResponseEntity<ErrorResponse> handleEntityNotFoundException( final HttpServletRequest request,
final EntityNotFoundException e ) {
return notFound( e );
}
protected ResponseEntity<ErrorResponse> notFound(
final Throwable e ) {
return new ResponseEntity<>( new ErrorResponse().error( e.getMessage() ), HttpStatus.NOT_FOUND );
}
}
If the client uses the accept header /*/ every works fine. Download works and if the entity is not existing an error is shown.
If the client uses the accept header application/octet-stream and the entity is existing the ExceptionHandler is not working cause of wrong media type and the service return a 500 error code. The exception is HttpMediaTypeNotAcceptableException.

How can I solve this?
Another exception handler for HttpMediaTypeNotAcceptableException didn't work.
EDIT: Here is a small example
https://github.com/MelleD/wrong-media-type-exception-handler-example
Start and try: http://localhost:8080/2
with accept header "application/octet-stream")
