37 * <p>Provides default implementation for {@link #getServerLocation()} that hides user credentials from uri, if any
38 *
39 * <p>Present method implementations are not expected to be invoked and do nothing, this may change in future to return
40 * reasonable error objects. New methods, added to {@link Connector}, will get default implementation in this class as well.
