[antlr-interest] matching identifiers in JavaLexer

[Doug Orleans]

Hi, I just switched over to ANTLR after a long time with JavaCC.  Open 
source rules!

Anyway, in the sample Java grammar provided with ANTLR (in
examples/java/java/java.g), the IDENT rule probably ought to use
java.lang.Character.isJavaIdentifierStart(char) and
java.lang.Character.isJavaIdentifierPart(char).
I just ran across them myself, and they look useful for Unicode
lexing.
