[antlr-interest] Problem with x: (A)(B)? ;

[dotlessbraille]

I have a question about the simple parser rule
x: (A)(B)? ;
The generated Java for the rule requires an
EOF if there is not a B. What am I doing wrong?

match(A);
switch ( LA(1)) {
 case B:			
  match(B);			
  break;			{
 case EOF:
  break;	
 default:
  throw new NoViableAltException(...);
}	

Thanks!
