The class or interface that declared the resolved field is initialized per JVMS `getStatic` and `putStatic`. So I think `Parent` is initialized but not `Child`. @PaulSandoz can confirm.

Yes, confirmed (verified both with explicit field access, `Child.value`,  and access using a direct method handle).
