Sorry, I dont have the exact code at hand anymore, since it didn't work.
(The point is, that the Decoder needs to extend ReplayingDecoder instead of
FrameDecoder to work in my setup).

BUT, it was basically like this:

public class TracingFrameDecoder extends FrameDecoder {

	private final List<TracingSignal> tracingSignals = new
LinkedList<TracingSignal>();

	@Override
	protected Object decode(ChannelHandlerContext ctx, Channel channel,
ChannelBuffer buffer) throws Exception {
		System.out.println("converted buffer class: " + buffer.getClass());
		System.out.println("converted buffer byte order: " + buffer.order());

		if (buffer.readableBytes() < 5) {
			return null;
		}

		buffer.markReaderIndex();

		buffer.readByte(); // over-read endianess byte

		final long messageSize = buffer.readUnsignedInt();

		if (buffer.readableBytes() < messageSize) {
			buffer.resetReaderIndex();
			return null;
		}

		tracingSignals.clear();

                // read bytes and fill tracingSignals

		return Collections.unmodifiableList(tracingSignals);
	}

}
