Spring edit exception list type as Exception instead of Throwable

I've changed the exception list type from Throwable to Exception. It's more clear when @ExceptionHandler annotation use.

@poutsma any thoughts? This is used primarily with Spring MVC where the HandlerExceptionResolver accepts Exception. Theoretically the annotation could be used elsewhere but perhaps it's worth aligning it more closely with Spring MVC.

@rstoyanchev Indeed, since the HandlerExceptionResolver only accepts Exception, it makes sense to use that in @ExceptionResolver as well. Unfortunately, that would break backward compatibility, I think.

hi~ any updates on this issue? Though that would break backward compatibility, that method only accepts Exception. I may think no one use throwable(or Error) type, so it doesn't cause any other issues.

The exception is now also used in WebFlux which does support Throwable.
