/**
 * Occurs when a service invocation did not complete cleanly.
 * 
 * A service invocation completes cleanly if
 * 

 * A response is returned from the service, or
 * An exception generated within the service is successfully received and
 * re-thrown in the client.
 * 
 * 
 * 
 * 
 * A service invocation can fail to complete cleanly for many reasons, including
 * 

 * The network connection to the server is unavailable
 * The host web server is not available
 * The server is not available
 * 
 * 
 * 
 * 
 * Note that it is 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.
