MonetaryConversions functions of java-money module do not work

Question

JavaFX Application raises an error when I try to call any MonetaryConversions function. The error message cointains

org.javamoney.moneta.spi.loader.ResourceCache: module org.javamoney.moneta does not declare uses org.javamoney.moneta.spi.loader.LoaderService: Provider org.javamoney.moneta.spi.loader.DefaultLoaderService could not be instantiated

Ther error occurs when I call (javax.money.convert.MonetaryConversions was imported):

System.out.println(MonetaryConversions.getDefaultConversionProviderChain());

Module-info.java contains:

requires java.money;
requires org.javamoney.moneta;

Also when I call another java-money function from another class it works. For example:

System.out.println(Monetary.getCurrency("USD"));

Please tell me what am I doing wrong?
