      Description

      I use the following code to dynamically determine if a class is an embeddable:

      Class c = Class.forName(s);
      ManagedType type = metamodel.managedType(c);
      if (type.getPersistenceType() == Type.PersistenceType.EMBEDDABLE) {
      logger.debug("" + c + " is an Embeddable.");
      // do somthing with the embeddable
      }
      else if (type.getPersistenceType() == Type.PersistenceType.ENTITY) {
      logger.debug("" + c + " is an Entity.");
      // do somthing with the entity
      }

      but when I use this code for an Embeddable, I always get "xxx is an Entity" logged.

      After examining the source code, I found "MetamodelImpl.instantiate" method will always put embeddable to both "embeddables" and "entities" containers, but "MetamodelImpl.managedType" method will first search "entities" and then "embeddables" for a persistence class, thus, "Entity" type will be returned for a ACTUAL Embeddable class.

      Hope this can be fixed.
