Michael McCandless commented on LUCENE-1542:
--------------------------------------------
Alas, this looks like a dup of LUCENE-1255, where we at first did a fix (like
this one) but then decided it was not back-compatible and so reverted it.
However, if that first token (with posIncr=0) also has a payload, it appears to
be particularly disastrous, since the way we encode a payload (by left-shifting
the position delta by 1 bit) does not preserve the -1, right?
> Lucene can incorrectly set the position of tokens that start a field with
> positonInc 0.
