> Class {{Resource}} has three sub classes(FixedValueResource,
> LightWeightResource, and ResourcePBImpl). Only FixedValueResource handle
> long-to-int casting nicely. The other two didn't. This bug is introduced by
> resource type feature and causes several unit test failures. For example:
> {code}
