Description

When Web Designer invokes ServletUtil.existsProcessImageInGuvnor(), the method successfully returns but the server side (Guvnor REST API) throws a SocketException because the caller closes a socket before reading response data.

			_logger.error(e.getMessage());

	}

The exception is observed only in Windows7 so far. It's likely up to HttpURLConnection implementation.
