-------------------------------------
Hi Joe, your patch looks correct to me, thanks! (btw, we do not need to add the
casts for trunk, as it uses java 5, but if/when backported to 2.9.x we can add
them).
I think we need to do the same thing with NGramTokenFilter, it looks broken too
in the same way. I'll take your patch and see if i can add fixes to that one
too... and both these filters need better tests to ensure these offsets work.
Thanks for the bug report and the fix!

> i ran into a problem while using the edgengramtokenfilter, it seems to report
> incorrect offsets when generating tokens, more specifically all the tokens
> have offset 0 and term length as start and end, this leads to goofy
> highlighting behavior when creating edge grams for tokens beyond the first
> one, i created a small patch that takes into account the start of the
> original token and adds that to the reported start/end offsets.
