[antlr-interest] lexer Code too large

["Paul Bouché (NSN)"]

Hi,

I have a rather complex lexer and I arrived at a state where I cannot 
reduce the rules anymore. When I try to compile the lexer I get the 
following exception:
StringPropsLexer.java:3444: code too large
public int specialStateTransition(int s, IntStream _input) throws 
NoViableAltException {
^
1 error

I added backward compatibility for unquoted strings which complicates 
the lexer obviously. Is there a way I can avoid this problem? The rule 
in questions this:
USTRING : /* backward compatibility... added, should support all 
simulation props semantics
           * the other tokens are listed here to ensure that the last 
match-everything alternative is disabled for
           * tokens that should be matched as they are if they are by 
themselfes, i.e.
           * i = 3 is still matched as a number and not as an ustring
           * k = ::1.2.3.4 should still be matched as an ip not as a 
ustring etc. */
     {foundFirstEquals}?=>
     ( NUMERIC ~('\.' | DIGIT_ | DL_ | '\n' | CB_ | CL_ | ')') USTRINGEND_
     | USTRINGBEGIN_ USTRINGEND_
     )
     { foundFirstEquals = false; }
    ;

I am using ANTLR 3.11 / ANTLRWorks 1.2.2.

Thanks,
Paul
