Maybe this test case will be better : [^hhh-5024.zip]
You can see the log message on the launching of junit : 
bq. HHH015011: Unable to locate static metamodel field : org.hibernate.test.ProductAttribute_#key

> The embeddable class {{CustomerId}} (see attached ZIP) inherits from the base class {{AbstractIdentity}} (annotated with {{@MappedSuperclass}}). The metamodel classes for these two classes are correctly generated:
> {code:title=AbstractIdentity_.java|borderStyle=solid}
> import javax.persistence.metamodel.SingularAttribute;
> import javax.persistence.metamodel.StaticMetamodel;
> @StaticMetamodel(AbstractIdentity.class)
> public abstract class AbstractIdentity_ {
> public static volatile SingularAttribute<AbstractIdentity, String> id;
> }
> {code}
> and
> {code:title=CustomerId_.java|borderStyle=solid}
> import javax.persistence.metamodel.StaticMetamodel;
> @StaticMetamodel(CustomerId.class)
> public abstract class CustomerId_ extends AbstractIdentity_ {
> }
> {code}
> When building the entity manager factory, {{MetadataContext#registerAttribute}} (line 378) tries to resolve the field {{CustomerId_.id}} using {{Class#getDeclaredField}}. This results in a {{NoSuchFieldException}} because the field is declared in the super class {{AbstractIdentity_}}.
> Proposed solution: Since all field declarations in the metamodel are public, the {{Class#getField}} method should be used instead.
