/**
 * This exception signals the caller that the operation cannot continue because
 * bytesProduced need to be read from the underlying {@link ByteChannel}, the channel is
 * non-blocking and there are no bytesProduced available. The caller should try the
 * operation again, either with the channel in blocking mode of after ensuring
 * that bytesProduced are ready.
 * 
 * For {@link SocketChannel}s, a {@link Selector} can be used to find out when
 * the method should be retried.
 * 

 * Caveat: Any {@link TlsChannel} I/O method can throw this exception. In
 * particular, write may want to read data. This is because TLS
 * handshakes may occur at any time (initiated by either the client or the
 * server).
 * 
 * This exception is akin to the SSL_ERROR_WANT_READ error code used by OpenSSL.
 *
 * @see 
 * OpenSSL error documentation
