Bad responce format in ExchangeRates().toFiat

[POSTAL5532]

Hey. Today I sat down to study your api. So there was a small problem in the example line:
BigDecimal BTCToUSD = exchange.toFiat("USD", new BigDecimal(100000000)); - throw

java.lang.NumberFormatException
at java.math.BigDecimal.(BigDecimal.java:494)
at java.math.BigDecimal.(BigDecimal.java:383)
at java.math.BigDecimal.(BigDecimal.java:806)
at info.blockchain.api.exchangerates.ExchangeRates.toFiat(ExchangeRates.java:96)

I ran the code in debug mode and found that in the line
return new BigDecimal(response);
in ExchangeRates().toFiat() in response, the value is returned in the following form: 819,060,000,000. I'm not a very experienced developer, but it seems to me that BigDecimal can not process commas in this sense. I will be glad to any answer. Thank you and sorry for my english)

public class CustomExchangeRates extends ExchangeRates {

@Override
public BigDecimal toFiat(String currency, BigDecimal value) throws APIException, IOException {
    Map<String, String> params = new HashMap();
    params.put("currency", currency);
    params.put("value", String.valueOf(value.multiply(BigDecimal.valueOf(100000000L))));
    String response = HttpClient.getInstance().get("frombtc", params);
    response = response.replaceAll(",", "");
    return new BigDecimal(response);
}

}

It's work for me!
