Is there a reason build() requires Long id instead of long id?

Several domain classes in the project I'm working on were written with "long id", and it looks like build-test-data is not saving instances of them when I call build(...). They do save if I switch them to Long. Is there a reason build-test-data isn't handle both situations?

I'll take a look at this, I've not come across this scenario. I'm a little surprised Grails allows it.
