[antlr-interest] Antlr could not analyze decision - intermittent

[Jon Schewe]

I get the following error 5 out of 6 times when I run antlr on the same 
grammar file without changing anything.  Why don't I get the error 
everytime?  This makes it very hard to debug if my changes will fix 
anything. 

BTW I've already added options {k=1;} to the rule that this refers to 
and I have syntatic predicates to resolve the issues.

     [java] warning(205): 
src/com/honeywell/htc/schedinfra/pconstraint/parser/GHOCES.g:200:5: 
ANTLR could not analyze this decision in rule constraintDecl; often this 
is because of recursive rule references visible from the left edge of 
alternatives.  ANTLR will re-analyze the decision with a fixed lookahead 
of k=1.  Consider using "options {k=1;}" for that decision and possibly 
adding a syntactic predicate.
