Subject [jira] Commented: (LUCENE-2643) StringHelper#stringDifference is wrong about supplementary chars
Date Wed, 20 Oct 2010 08:09:22 GMT


Michael McCandless commented on LUCENE-2643:

bq. Lets drop it from 4.0 and 3.x and deprecate in the 3.0 branch so if we do a 3.0.3 release
one day people get a heads up.

I think doing anything in 3.0.x is optional here... above & beyond the call of duty ;)

And we should drop it in 3.x and 4.0.

> StringHelper#stringDifference does not take supplementary characters into account. Since
this is not used internally at all we should think about removing it but I guess since it
is not too complex we should just or fix it for bwcompat reasons. For released versions we
should really fix it since folks might use it though. For trunk we could just drop it.
