[antlr-interest] Oh my, code too large

[John Ridgway]

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.

Peace
- John
