Description

An exception occurs if you add the @Strategy annotation on a field of an @Embeddable or @MappedSuperclass (not part of an @ElementCollection).
The patch OPENJPA-1556.patch does not fix the problem.

<openjpa-2.0.0-beta2-rexportiert fatal user error> org.apache.openjpa.persistence.ArgumentException: Attempt to map "jpa.test.domain.TestEntityBase.testEnumSimple" failed: the owning entity is not mapped.

To be more concrete. I try to change the default enum handling using an own EnumValueHandler. The Handler is working if you add
the @Strategy to the @Entity. Adding @Strategy on a field in a @MappedSuperclass leads to the above exception.

@javax.persistence.Entity
@javax.persistence.Table(name = "TESTENTITY")
public class TestEntity extends TestEntityBase {
...
}

@MappedSuperclass
public abstract class TestEntityBase {
@Column(name = "TESTENUMSIMPLE")
@Enumerated(javax.persistence.EnumType.STRING)
@Strategy("jpa.test.domain.EnumStrategy")
private TestEnumSimple testEnumSimple;
...
}

You get the same Exception if you add the @Strategy to a @Embeddable and I also tried a own simple StringValueHandler with the same result.
