Bug 372092

Description David Morer 2012-02-21 04:47:14 EST

Build Identifier: 2.3.2.v20111125-r10461

When I have a entity hierarchy with generics and embedded key, exceptions are raised when the persistence.xml file is processed.

1st error case (two level of parents) :
----------------------------------------
 *  
 *  Classes :
 *  
 *  @Embeddable
 *  public class MyPK
 *       private int key;
 *  
 *  @Entity
 *  public class MyEntity extends AbstractMiddleEntity<MyPK>
 *  
 *  @MappedSuperclass
 *  public abstract class AbstractMiddleEntity<PK> extends AbstractBaseEntity<PK>
 *  
 *  @MappedSuperclass
 *  public abstract class AbstractBaseEntity<PK>
 *      @EmbeddedId
 *      private PK id;
 *  

Exception raised :

java.lang.IndexOutOfBoundsException: Index: 8, Size: 8
 *   at java.util.ArrayList.RangeCheck(ArrayList.java:547)
 *   at java.util.ArrayList.get(ArrayList.java:322)
 *   at org.eclipse.persistence.internal.jpa.metadata.accessors.objects.MetadataAsmFactory.resolveGenericTypes(MetadataAsmFactory.java:165)   at org.eclipse.persistence.internal.jpa.metadata.accessors.classes.ClassAccessor.resolveGenericTypes(ClassAccessor.java:1611)
 *  at org.eclipse.persistence.internal.jpa.metadata.accessors.classes.EntityAccessor.discoverMappedSuperclassesAndInheritanceParents(EntityAccessor.java:282)

2nd error case (one level of parent) :
-------------------------------------
 * 
 *  Classes :
 *  
 *  @Embeddable
 *  public class MyPK
 *       private int key;
 *       
 *  @Entity
 *  public class MyEntity extends AbstractBaseEntity<MyPK>
 *  
 *  @MappedSuperclass
 *  public abstract class AbstractBaseEntity<PK>
 *      @EmbeddedId
 *      private PK id;
 *

Exception raised :

org.eclipse.persistence.exceptions.ValidationException
Exception Description: The Entity class [class be.smals.eclipselinktestcase.AbstractBaseEntity] has an embedded attribute [id] of type [class java.lang.String] which is NOT an Embeddable class. Probable reason: missing @Embeddable or missing <embeddable> in orm.xml if metadata-complete = true
