java - JAX RS ExceptionMapper is not used when doing StreamingOutput -

i have exception mapper in jax-rs application (jersey 1.19):

public class illegalargumentexceptionmapper     implements exceptionmapper<illegalargumentexception> {   @override   public response toresponse(illegalargumentexception e) {     response.status status = response.status.bad_request;     return response.status(status).entity(e.getmessage()).build();   } } 

and works correctly (the client http status 400) in case:

@get @path("/test1") public string test2() {   throw new illegalargumentexception("exception 1"); } 

but if streaming output that:

@get @path("/test2") public string test2() {   return new streamingoutput() {     @override     public void write(outputstream output) {       throw new illegalargumentexception("exception 2");     }   }; } 

then exception mapper not used, , client gets http status 500. how can force use exception mapper?
