[antlr-interest] lexical nondeterminism Or rule contain rule

[idontwantanidwith2000init]

Hi,
I have one lexical rule that contains another.
STRING: ( 'a'..'z'|'A'..'Z' )+
	;

STRING_LITERAL
  : '"'!
    ( '\\' .
    | ~('"'|'\n'|'\r')
    )*
    ( '"'!
    | // nothing -- write error message
    )
	;

I'm using eclipse.
It's warning me that I have nondeterminism but I'm not using 
STRING_LITERAL and STRING in the same parser rule.
What can I do to avoid this nondeterminism?

Tal.
