Fixed version (ground truth):

      energyValue=(float)parseDoubleWithMin(commandSender,args[2],0);
    }

    if (itemStack != null) {
      WrappedStack wrappedStack=WrappedStack.wrap(itemStack);
      EnergyValue newEnergyValue=new EnergyValue(energyValue);
      if (wrappedStack != null && newEnergyValue != null) {
        if (Float.compare(newEnergyValue.getValue(),0) > 0) {
