It does work for the C++ targeted grammar, but it
doesn't for the Java targeted one which I am currently
working on:

AdaParser.java:7061: exception antlr.RecognitionException is never 
thrown in body of corresponding try statement

This happens while translating the method empty_component_items()
which is produced by the rule

empty_component_items :
  { #empty_component_items =
    #(#[COMPONENT_ITEMS,
       "COMPONENT_ITEMS"], #empty_component_items); }
  ;

Thanks,

Oliver
