[Resteasy-users] JAX-RS 2.0 - ContainerResponseFilter - UnhandledException

[Frode A. <fro...@gm...>]

What is the correct behavior when a JAX-RS method throws an exception that are not mapped by a ExceptionMapper and a ContainerResponseFilter is provided?

		@Path("/") @Produces(value = { MediaType.TEXT_PLAIN }) 
	public class ApiResources {
	
		@GET
		@Path("throwIllegalArgumentException")
		public String getThrowIllegalArgumentException() {
			throw new IllegalArgumentException( "HELLO from throwIllegalArgumentException" );
	
	}

	@Provider
	public class MonitorFilter implements ContainerResponseFilter {
		@Override 
		 public void filter( ContainerRequestContext requestContext, 
				 ContainerResponseContext responseContext ) throws IOException {
			System.out.println(“Resource returned status=“ + responseContext.getStatus());
		}
	}
		
Tested the code in wildfly-8.0.0.Alpha4 and the ContainerResponseFilter#filter method was not called. It was only called after a ExceptionMapper for IllegalArgumentException was provided.

@Provider
public class IllegalStateExceptionExceptionMapper implements ExceptionMapper<IllegalStateException> {
	@Override
	public Response toResponse( IllegalStateException e ) {
		return Response.status( Response.Status.INTERNAL_SERVER_ERROR ).entity( e.getMessage() )
				.build();
	}
}
