in org.hibernate.mapping.PersistentClass some 2 performance issues can be fixed
-------------------------------------------------------------------------------

                 Key: HHH-5920
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5920
             Project: Hibernate Core
          Issue Type: Improvement
    Affects Versions: 3.6.1, 3.5.5, 3.3.2, 3.2.7, 3.1.3, 3.0.5
            Reporter: Christoph Weißenborn
         Attachments: org.hibernate.mapping.persistentclass.patch

3 performance issues in org.hibernate.mapping.PersistentClass:

1. The mappedClass is loaded again and again calling ReflectHelper.classForName(className). The mapped class is not changed so it should be hold as member variable.

2. Method getProperty(String, Iterator) uses a MappingException which is ignored in getRecursiveProperty(String, Iterator). This makes the recursion more expensive than required.

3. Method getProperty calls StringHelper.root( propertyName ) for every property. Simply change the while in if do while.

A fix is provided as attachment.
