--------------------------------------

             Summary: camel-servlet + camel-http4 with null body causes "Stream closed" IOException
                 Key: CAMEL-13886
                 URL: https://issues.apache.org/jira/browse/CAMEL-13886
             Project: Camel
          Issue Type: Bug
          Components: camel-http-common, camel-http4, camel-servlet
    Affects Versions: 3.0.0.M4, 2.25.0
            Reporter: Tadayoshi Sato
            Assignee: Tadayoshi Sato


A Rest DSL route like the following causes {{java.io.IOException: Stream closed}} when invoked at http://localhost:8000/test/proxy:
{code:java}
        rest("/test")
                .get("/proxy")
                .to("direct:callInternalRestService");

        from("direct:callInternalRestService")
                .setHeader(Exchange.HTTP_METHOD, constant("DELETE"))
                //.setBody(constant("")) // workaround for null body and http4 component
                .to("http4://localhost:9000/test?bridgeEndpoint=true")
                .log("${body}");
{code}

The error stacktrace:
{code}

{code}

This seems to happen only when Tomcat is used as the container with Spring Boot. Undertow doesn't cause such an issue.
