[antlr-interest] * (zero or more) not matching greedily

The relevant stuff from a grammar:
category: (alphanum|'+'|'_'|DOT) ( alphanum|'+'|'_'|DOT|'-')* {
System.out.println($category.text); };
alphanum: LOWER|UPPER|DIGIT;
DOT : '.';
DIGIT : '0'..'9';
LOWER : 'a'..'z';
UPPER : 'A'..'Z';
Why does it only take the first character for category? Isn't * supposed
to be greedy? I also tried adding options {greedy=true;} to the subrule
but it doesn't make a difference.
