> 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}

> -This seems to happen only when Tomcat is used as the container with Spring
> Boot. Undertow doesn't cause such an issue.-
> The real root cause is that when an exchange has an {{HttpMessage}} with
> {{null}} body as its out message, then the next time
> {{Exchange.getMessage()}} is invoked the {{HttpMessage}} is tricked by the
> {{null}} body and tries to create body again with the already closed request
> input stream.
