> We removed this before because of LUCENE-2828,
> but the problem there was the delegator (not the lengthNorm method).
> TFIDFSim requires byte[] norms today. So its computeNorm should be final,
> calling lengthNorm() that returns a byte.
> This way there is no possibility for you to do something stupid.
