[antlr-interest] unexpected end of subtree

[Mr Torsten Curdt]

Can someone please explain why the following
snippet generates an "unexpected end of subtree"
warning? Everything else seem to be fine.

keyvalue returns [ Object o ]
  {
    o = null;
    String kn;
    Object kv;
  }
  : { java.util.HashMap map = new java.util.HashMap();
o = map; }
    ( 
      #(KEY kn=literal kv=literal) {
        map.put(kn,kv);        
      }
    )+
  | #(VALUE kv=literal) {
      o = kv;
    }
  ;

Is it because (#KEY)+ is unbound? I assume
I get the warning when the end of the childs
are reached.

cheers

Torsten
