I think there is an issue in JettyHttpProducer.

    public boolean process(Exchange exchange, final AsyncCallback callback) {
        JettyContentExchange httpExchange = null;
        try {
            httpExchange = createHttpExchange(exchange, callback);
            doSendExchange(client, httpExchange);
        } catch (Exception e) {
            // error occurred before we had a chance to go async
            // so set exception and invoke callback true
            return true;

        // we should continue processing this asynchronously
        return false;

createHttpExchange(exchange, callback) may open an input stream and
set it to httpExchange. When something goes wrong in doSendExchange,
this input stream may not be closed. So, I put a finally block there
which checks if the input stream in available in httpExchange and if
so, closing it. That released the file. Or something of this kind
could go into doSendExchange.
