David Smiley commented on LUCENE-2504:
--------------------------------------

Yonik, just curious, how do you know what HotSpot is doing?  Empirically based on performance
numbers?  HotSpot code or documentation that spells out exactly when it inlines?  Or is there
some tool or diagnostic capability to learn this information?
