exception handling - ExceptionHandler returning JSON or XML not working in spring mvc 3 -

code this:

   @controller     public class testcontroller {          @requestmapping(value = "/testerror", method = requestmethod.get)         public @responsebody errorto testerror(httpservletrequest request,httpservletresponse response) {            throw new abcexception("serious error!");         }           @exceptionhandler(abcexception.class)         public  @responsebody errorto handleexception(abcexception ex,                 httpservletrequest request, httpservletresponse response) {             response.setstatus(response.sc_bad_request);             return new errorto(ex.getmessage());         }        @requestmapping(value = "/test", method = requestmethod.get)     public @responsebody errorto test(httpservletrequest request,                                        httpservletresponse response) {         errorto error = new errorto();         error.setcode(-12345);         error.setmessage("this test error.");         return error;     }  } 

when tried curl -h "accept:application/json" -v "http://localhost.com:8080/testerror" got error: org.springframework.web.servlet.mvc.annotation.annotationmethodhandlerexceptionresolver - not find httpmessageconverter supports return type [class com.kibboko.poprocks.appservices.dtos.errorto] , [application/json]

but if try curl -h "accept:application/json" -v "http://localhost.com:8080/test", worked , returned json response. "application/xml" worked too.

is there special exception handler need take care of can work json or xml? thanks!

seems known spring bug (fixed in 3.1 m1)
