[antlr-interest] Strange parse result

I have a small test grammar:
grammar test_grammar;
testrule : t*;
t: RULE_EQUALS | RULE_ABSTRACT_LITERAL | RULE_WS ;
RULE_EQUALS : ':=';
RULE_ABSTRACT_LITERAL : ('0'..'9')+ (':' ('0'..'9')+ ':')?;
RULE_WS : (' '|'\t')+;
When I debug this grammar (with ANTLRWorks 1.4.2 using ANLTR 3.3) I feed it
the input (no spaces)
15:=0
and it doesn't parse my input correctly. When I change the input to (adding
space before ':=')
15 :=0
it parses successfully. Any ideas what I'm missing here?
