Buggy source:

  if (regNames.containsKey(registerNumber)) {
    rn.name=regNames.get(registerNumber);
  }
  value.moreSrc.add(new GraphSourceItemPos(this,0));
  boolean define=!variables.containsKey("String_Node_Str" + registerNumber);
  variables.put("String_Node_Str" + registerNumber,value);
  if (value instanceof DirectValueActionItem) {
    if (((DirectValueActionItem)value).value instanceof RegisterNumber) {

Fixed version (ground truth):

  RegisterNumber rn=new RegisterNumber(registerNumber);
  if (regNames.containsKey(registerNumber)) {
    rn.name=regNames.get(registerNumber);
  }
  value.moreSrc.add(new GraphSourceItemPos(this,0));
  boolean define=!variables.containsKey("String_Node_Str" + registerNumber);
  if (regNames.containsKey(registerNumber)) {
    define=false;
  }
  variables.put("String_Node_Str" + registerNumber,value);
  if (value instanceof DirectValueActionItem) {
    if (((DirectValueActionItem)value).value instanceof RegisterNumber) {
      if (((RegisterNumber)((DirectValueActionItem)value).value).number == registerNumber) {
        stack.push(value);
        return;
      }
    }
  }
