Response is not returned from Camel's onException handler

[ozkin]

Simple test application has one composite service with HTTP binding and one Camel route implementing the service.

The route has own exception handling and transforms the response to "error" string in case if an exception is caught.

For some reason the response is not returned back to the client (via HTTP binding) and client gets hang waiting for the response. Any idea why is that?

Below is the route definition. I have also attached a complete project. SwitchYard version is 1.1.

The idea is to return a different custom response in case of an exception..

public void configure() {

        from("switchyard://TestService")

            .onException(Exception.class)

                .handled(true)

                .log("Exception: ${exception}")

                .transform().simple("error")

            .end()

            .log("Received message for 'TestService' : ${body}")

            .process(new Processor() {

                @Override

                public void process(Exchange exchange) throws Exception {

                    throw new Exception("failed");

                }

            });

    }

I tried it on current upstream master of SwitchYard and got this

[tomo@tomo-t530 switchyard-http-test]$ telnet localhost 8080

Trying 127.0.0.1...

Connected to localhost.

Escape character is '^]'.

GET /foo HTTP/1.0

HTTP/1.1 200 OK

Server: Apache-Coyote/1.1

Content-Length: 5

Date: Mon, 07 Dec 2015 00:48:21 GMT

Connection: close

error

And server log

09:48:21,953 INFO  [route1] (http-/127.0.0.1:8080-1) Received message for 'TestService' :

09:48:21,958 INFO  [route1] (http-/127.0.0.1:8080-1) Exception: java.lang.Exception: failed

It seems to be working as expected?

As I mentioned we use version 1.1.0.Final. Then it seems there is a bug in that version... (

For me the following does not come at all:

HTTP/1.1 200 OK

Server: Apache-Coyote/1.1

Content-Length: 5

Date: Mon, 07 Dec 2015 00:48:21 GMT

Connection: close

error

And eventually SwitchYard logs:
