/**
 * A special exception that tells the {@link ProtocolDecoder} can keep
 * decoding even after this exception is thrown.
 * <p>
 * Once {@link ProtocolCodecFilter} catches any other type of exception
 * than {@link RecoverableProtocolDecoderException}, it stops calling
 * the {@link ProtocolDecoder#decode(org.apache.mina.core.session.IoSession,
 *        org.apache.mina.core.buffer.IoBuffer, ProtocolDecoderOutput)}
 * immediately and fires an {@code exceptionCaught} event.
 * <p>
 * On the other hand, if {@link RecoverableProtocolDecoderException} is thrown,
 * it doesn't stop immediately but keeps calling the {@link ProtocolDecoder}
 * as long as the position of the read buffer changes.
 * <p>
 * {@link RecoverableProtocolDecoderException} is useful for a robust
 * {@link ProtocolDecoder} that can continue decoding even after any
 * protocol violation.
