HTTPConduit reads response before it completes sending request
--------------------------------------------------------------

                 Key: CXF-3570
                 URL: https://issues.apache.org/jira/browse/CXF-3570
             Project: CXF
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.4
            Reporter: David Liu
            Priority: Critical


Hi,

  In CXF 2.4, HTTP Conduit has a new debug log as below. However, this logging 
message can cause HTTPConduit reads the  response before it completes sending 
request, and it results in an IOException in the client side.
  The reason is that the method *connection.getContentType()* will trigger 
httpconnect to send current data to the HttpServer and want the server to 
return the response, so the server thinks the client complete the whole request 
and the server just reply nothing and closes the http connection.


Code in HttpConduit.java
{code}
        protected void onFirstWrite() throws IOException {
            ...            
            if (LOG.isLoggable(Level.FINE)) {
                LOG.fine("Sending "
                    + connection.getRequestMethod() 
                    + " Message with Headers to " 
                    + connection.getURL()
                    + " Conduit :"
                    + conduitName
                    + "\nContent-Type: " + connection.getContentType() + "\n");
            }
        }
{code}

  To reproduce the issue: please create a simple web service in cxf 2.4 and 
enable its debug log, and then use a generated proxy client to call the http 
service, then you can see the error below.
