JFlex is a flex-like lexer generator for Java with emphasis on speed and full Unicode support. It works as a standalone tool or together with the LALR parser generators CUP and BYacc/J. JFlex has support for some not so usual features like negation in regular expressions and nested input streams. It can also read JLex specifications unchanged.


This release fixes all known bugs of previous JFlex versions and adds support for Java generics.
