      Description

      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" of type "class org.apache.openjpa.datacache.DataCachePCDataImpl".

      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.
