Hi,

just wanted to say that java 1.5 features can be supported. The
following generates and compiles fine:


@parser::members {

private List<String> _collectedErrorMessages = new ArrayList<String>();

public boolean hasCollectedErrorMessages() {
  return getCollectedErrorMessages().size() > 0;
}

public List<String> getCollectedErrorMessages() {
  return _collectedErrorMessages;
}

@Override
public void emitErrorMessage(String msg) {
  super.emitErrorMessage(msg);
  _collectedErrorMessages.add(msg);
}

}


best wishes,
Oti.
