The fix is to make sure the amount is being cast to Number, then the .intValue() method is used to get the int value of the amount. 

if (args.containsKey("amount")) {
            amount = ((Number) args.get("amount")).intValue();
}

I assume by that you mean that it was resolved. Either way it is misfiled.
