[antlr-interest] another nondeterminism question

[Adrian Sandor]

why do I get a nondeterminism warning for this grammar:

class l1 extends Lexer;
options{k=2;}
protected A: 'a' | "bb";
B: 'b';
S: (A)+;

but I don't get any warning when I change S to:

S: A (A)+;

and how can I solve it for the first case?
I tried many things but to no avail...

thanks
Adrian
