/**
 * Occurs when a service invocation did not complete cleanly.
 * <p>
 * A service invocation completes cleanly if
 * <ol>
 * <li>A response is returned from the service, or</li>
 * <li>An exception generated within the service is successfully received and
 * re-thrown in the client.</li>
 * </ol>
 * </p>
 * 
 * <p>
 * A service invocation can fail to complete cleanly for many reasons, including
 * <ol>
 * <li>The network connection to the server is unavailable</li>
 * <li>The host web server is not available</li>
 * <li>The server is not available</li>
 * </ol>
 * </p>
 * 
 * <p>
 * Note that it <em>is</em> possible for this exception to be thrown even if
 * the service was invoked successfully on the server. This could be the case,
 * for example, if a network failure happened after the invocation request was
 * sent but before the response was received.
