> The second call to an asynchronous web method is failing when using the JDK
> HttpClient-based conduit and allowChunking set to false.

> Logs show that the while the first request has correct conetnt-length, the
> second request has Transfer-encoding: chunked, and the body is not sent at
> all. Here are 3 requests received by the server (WSDL and two web methods):

> I'm attaching a test class that demonstrates the issue.
> For the failure to happen, we need
> * to use the new default HttpClient-based conduit (URLConnection-based
> conduit works)
> * {{allowChunking}} to be set to false (not set or set to true works)
> * an asyncronous service method to be used (synchronous method works)
