/**
* 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
