Fix Version/s: (was: 3.0.0)
3.0.1
3.0.1
> Metamodel generation of entity or mapped superclass
> ---------------------------------------------------
>
> Key: OPENJPA-2728
> URL: https://issues.apache.org/jira/browse/OPENJPA-2728
> Project: OpenJPA
> Issue Type: Bug
> Reporter: Karl Richter
> Priority: Major
> Fix For: 3.0.1
>
>
> A simple entity or mapped superclass with a generic type parameter causes the
> metamodel generation to fail because of syntax errors, e.g.
> {code:java}
> @MappedSuperclass
> public abstract class MyEntity2<T extends MyEntity> implements Serializable {
> private static final long serialVersionUID = 1L;
> @Id
> @GeneratedValue
> private Long id;
> private T myEntity;
> {code}
> causes the generation of
> {code:java}
> import java.lang.Long;
> import javax.persistence.metamodel.SingularAttribute;
> @javax.persistence.metamodel.StaticMetamodel
> (value=richtercloud.openjpa.generic.metamodel.MyEntity2.class)
> @javax.annotation.Generated
> (value="org.apache.openjpa.persistence.meta.AnnotationProcessor6",date="Sat
> Feb 03 20:59:32 CET 2018")
> public class MyEntity2_ {
> public static volatile SingularAttribute<MyEntity2,Long> id;
> public static volatile SingularAttribute<MyEntity2,T> myEntity;
> }
> {code}
> which is invalid because `T` isn't specified and thus unknown to the compiler.
> A SSCCE is provided at https://gitlab.com/krichter/openjpa-generic-metamodel.
> experienced with 3.0.0-SNAPSHOT
