We use @Entity and hbm.xml mapped classes.
{{EntityType persistEntityType = iceEntityManager.get(persistEntityName);
Attribute persistAttribute = persistEntityType.getAttribute(attributeName);
Class persistAttributeJavaTypeClass = persistAttribute.getJavaType();}}

After 5.3.4.Final these are no longer created for Mapped classes.
Mapped.hbm.xml/@Entity classes are used interchangeably through Maps.
