Sorry for my layte reply, we are in hard times now 
@Quentin It has nothing to do with classpath, it is a problem in IntelliJ plugin.
@Julien_HENRY I enabled verbose log:

I don’t see anything suspicious there.
This is the full block which reproduces the issue:
static {
final Function<Triple<CurrencyEnum, String, ImmutableMap.Builder<String, CurrencyEnum>>, Void> addCodeToBuilder
= new Function<Triple<CurrencyEnum, String, ImmutableMap.Builder<String, CurrencyEnum>>, Void>() {
void apply(final CurrencyEnum currency, final String currencyCode, final ImmutableMap.Builder<String, CurrencyEnum> mapBuilder) {
mapBuilder.put(currencyCode, currency);
final String currencyCodeUpper = currencyCode.toUpperCase();
if (!currencyCode.equals(currencyCodeUpper)) {
mapBuilder.put(currencyCodeUpper, currency);
}
}
@Nullable
@Override
public Void apply(final Triple<CurrencyEnum, String, ImmutableMap.Builder<String, CurrencyEnum>> input) {
apply(input.getKey1(), input.getKey2() != null ? input.getKey2() : input.getKey1().getCurrencyCode(), input.getKey3());
return null;
}
};
ImmutableMap.Builder<String, CurrencyEnum> currencyCodeMapBuilder = new ImmutableMap.Builder<String, CurrencyEnum>();
ImmutableMap.Builder<String, CurrencyEnum> currencyCodeForPageMapBuilder = new ImmutableMap.Builder<String, CurrencyEnum>();
for (CurrencyEnum currency : values()) {
addCodeToBuilder.apply(Triple.of(currency, (String) null, currencyCodeMapBuilder));
if (currency != GLD) {
addCodeToBuilder.apply(Triple.of(currency, currency.getCurrencyCodeForPage(), currencyCodeForPageMapBuilder));
}
}
currencyCodeMapBuilder.build();
}
