CXF Exception-Handling: error message is not included in Response

[J. Fiala]

Hi,

I just came across the Exception handling behaviour of CXF 3 and was 
wondering if this is intended:

1.) Passing simply a string as message results in message is not 
included in the response.

throw new InternalServerErrorException("message");

==> will return only Status: 500

Status : 500
Headers :
connection : close
Content-Length : 0
Date : Thu, 18 Aug 2016 13:23:42 GMT
Server : Apache-Coyote/1.1


2.) Passing a Reponse will result in the desired behaviour:

throw new 
InternalServerErrorException(Response.status(Status.INTERNAL_SERVER_ERROR).entity("message").build());

==> will return

Status : 500
Headers :
connection : close
Content-Length : 81
content-type : application/json
Date : Thu, 18 Aug 2016 13:24:33 GMT
Server : Apache-Coyote/1.1
Error message :
message

Is there a specific reason why the simpler form will not return the message?

3.) However, if any RuntimeException occurs during the call, CXF3 will 
by default return the complete stack trace to the client with Status 500.
Is there any way to prevent this (by using an Exception Handler or so...)?

Best regards,

Johannes
