Java Money get exchange rate hanging

Question

I was trying simple money conversion in using java money-api & moneta repository.

<dependency>
    <groupId>javax.money</groupId>
    <artifactId>money-api</artifactId>
    <version>1.1</version>
</dependency>
<dependency>
    <groupId>org.javamoney</groupId>
    <artifactId>moneta</artifactId>
    <version>1.4.2</version>
</dependency>

IMFHistoricRateProvider imf = new IMFHistoricRateProvider();

LocalDate now = LocalDate.now();
ExchangeRate exr = null;
long start = System.currentTimeMillis();
LocalDate date = LocalDate.parse("2021-05-25", DateTimeFormatter.ISO_LOCAL_DATE);
exr = imf.getExchangeRate(ConversionQueryBuilder.of().setBaseCurrency("EUR").setTermCurrency("USD").set(LocalDate.class, date).build());
System.out.println(exr.getFactor() + " ==" + (System.currentTimeMillis()-start));

Here exr.getFactor() method gives the exchange rate for the given date, but its getting hanged at a state for hours.

PF log at which its hanging.

It should give exchange rate from EUR to USD for the X local date from past.

Answer 1

I have change the dependence from moneta to more specific exchange rate provider moneta-convert-ecb

<dependency>
    <groupId>javax.money</groupId>
    <artifactId>money-api</artifactId>
    <version>1.1</version>
</dependency>
<dependency>
    <groupId>org.javamoney.moneta</groupId>
    <artifactId>moneta-core</artifactId>
    <version>1.4.2</version>
</dependency>
<dependency>
    <groupId>org.javamoney.moneta</groupId>
    <artifactId>moneta-convert-ecb</artifactId>
    <version>1.4.2</version>
</dependency>

Also changed

IMFHistoricRateProvider imf = new IMFHistoricRateProvider();

to

ExchangeRateProvider ecb = new ECBHistoricRateProvider();

All though this fix worked but it is just changing of provider from IMF to ECB.

Note : IMF was still behaving same.
