I'm not the OP. It works perfectly on my side, as reported yesterday.

The new APIs are really nice from a DSL point of view, especially the
natural id stuff. Thanks for your work on this.

IMHO, even if it's not a problem by itself, I think byId() should be
consistent with the rest of the API and return an interface. I don't
see any advantages to return the Impl in this case.

Have a nice day.
