-------------------------------------
+1
does the minimal jflex revision need to be bumped (currently r591 in READ_BEFORE_REGENERATING.txt) ?

> Newly released Unicode 6.0.0 contains some character property changes from the previous release (5.2.0) that affect word segmentation (UAX#29), and JFlex 1.5.0-SNAPSHOT now supports Unicode 6.0.0, so Lucene's UAX#29-based tokenizers should be updated accordingly.
> Note that the UAX#29 word break rules themselves did not change between Unicode versions 5.2.0 and 6.0.0.
