Azuo Lee updated OPENJPA-2377:
------------------------------

    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.
