Subject [jira] [Commented] (LUCENE-3179) OpenBitSet.prevSetBit()
Date Tue, 07 Jun 2011 22:36:58 GMT

Uwe Schindler commented on LUCENE-3179:
---------------------------------------

OK, so we can sefely remove BitUtil.pop and replace by the Java 5 method (maybe review again
the code in src.jar also for ntz). And if this one is an intrinsic in Java 6 its even faster.

Now we talk the same language :-)
