Error when removing embeddable entities from a persistent collection
--------------------------------------------------------------------

                 Key: OPENJPA-625
                 URL: https://issues.apache.org/jira/browse/OPENJPA-625
             Project: OpenJPA
          Issue Type: Bug
          Components: kernel
    Affects Versions: 1.1.0
         Environment: OpenJPA 1.1.0
Java 6
MySQL 5
Extended Persistence Context
DataCache enabled
            Reporter: Matthias Seidel


Say you have an EntityA which is annotated as @Embeddable and an EntityB which contains a
mapping like

@PersistentCollection(elementEmbedded = true, elementType = EntityA.class, fetch = FetchType.LAZY)
private List<EntityA> list;

Now if you remove an entry from the list of a persistent EntityB and commit the transaction
it leads to the following exception:

Caused by: <openjpa-1.1.0-runknown fatal user error> org.apache.openjpa.persistence.ArgumentException:
Could not locate metadata for the class using oid "org.apache.openjpa.datacache.DataCachePCDataImpl@8c248cb"

After some digging I think I found the cause in the AbstractPCData.toNestedFields method:

case JavaTypes.PC:
     if (vmd.isEmbedded())
        for (Iterator itr = data.iterator(); itr.hasNext();)
             ret.add(toEmbeddedField(sm, vmd, itr.next(), fetch, context));
// no break

should probably be:

case JavaTypes.PC:
    if (vmd.isEmbedded()) {
         for (Iterator itr = data.iterator(); itr.hasNext();)
              ret.add(toEmbeddedField(sm, vmd, itr.next(), fetch, context));
         return ret;
    }
// no break

At least it worked for me this way.
