[antlr-interest] Oh my, code too large

[Jim Idle]

IN 3.1 (coming soon now), you can take out parts of your grammar into
separate files, then use the import function to import say
‘xyzexpressions’ into your root grammar. You can use a snapshot of ANTLR
3.1 as it will be released quite soon. The imported grammars all occupy
their own class and so the issue goes away.

I have recently run into this (previously posted) problem and was
wondering what the status was?
There is a slight difference though, the error is found in a tree
grammar rather than a lexer.
 
"The problem is real.
Java effectively limits you to 65KBytes per method of byte-code.
The source of the limit is the definition of  the class files.
A class file includes, for each method, a table of  exception handlers,
and each of the entries in these tables includes the address
(in bytes relative to the beginning of the method) of the
beginning and end of the try-block, stored as two 16-bit integers.
There is no way around this.
I hope that there are people out there  who can make suggestions as to
how to modify your lexer to generate
less code."

      Sometimes ANTLR generates a lexer which will make javac choke on
      itself with a message resembling this:
       
       code too large
          public int specialStateTransition(int s, IntStream
      input)throws
            

NoViableAltException {
