RoundingMode of DefaultRoundingProvider hardcoded to HALF_EVEN

[jurriaan]

I've set the org.javamoney.moneta.Money.defaults.roundingMode property to HALF_UP but noticed that the rounding using Monetary.getDefaultRounding() still used HALF_EVEN when rounding.

I think this is due to the DefaultRoundingProvider having the default roundingMode set to HALF_EVEN instead of using the configuration.

See:

jsr354-ri/moneta-core/src/main/java/org/javamoney/moneta/spi/DefaultRoundingProvider.java

Line 59 in 3415a66

roundingMode = RoundingMode.HALF_EVEN;

Is this expected behavior?

Is that property documented anywhere? As far as I can tell, the spec compliant way to get a rounding with a client defined rounding mode is:

RoundingQueryBuilder.of()
  .set(RoundingMode.class, RoundingMode.HALF_Up)
  .build();

Edit: Just looked at org.javamoney.moneta.Money.defaults.roundingMode. This should only affect rounding when Money instances are used, and even then it's only used when the result of an operation exceeds the precision.
