[antlr-interest] Error in predicate logic

[Terence Parr]

Hi Harmut,

Hmm...that is suspicious:

ID   :
     (AA DIGIT) => AA
   | (AAB DIGIT) => AAB
   | ('a'..'z'|'A'..'Z') ('a'..'z'|'A'..'Z'|'_'|'0'..'9')+
   ;

AAB collides with 3rd alt as does AA so it should test synpred1 then  
synpred2 then 3rd alt (no pred).  Odd.

Adding to bug db.
