/**
 * This exception signals the caller that the operation cannot continue because bytesProduced need to be write to the underlying
 * {@link ByteChannel}, the channel is non-blocking and there are no buffer space available. The caller should try the operation
 * again, either with the channel in blocking mode of after ensuring that buffer space exists.
 *
 * 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, read may want to write 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_WRITE error code used by OpenSSL.
 *
 * @see 
 * OpenSSL error documentation
