Description

WebHook connector reads the HTTP body as InputStream and replaces it with Syndesis specific JSON containing parameters/body. The binding (org.apache.camel.http.common.DefaultHttpBinding) that created the message (org.apache.camel.http.common.HttpMessage) reads from the InputStream of the HttpServletRequest and closes the stream. If the next processor in the exchange is a org.apache.camel.processor.Pipeline org.apache.camel.util.ExchangeHelper::copyResults is invoked and ends up calling HttpMessage::createBody that ends up calling DefaultHttpBinding::parseBody reading the InputStream for the second time. At this time the InputStream is already closed so UT010029: Stream is closed is reported.
