java.lang.ClassCastException in JavassistLazyInitializer.getProxy
-----------------------------------------------------------------

                 Key: HHH-6874
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6874
             Project: Hibernate Core
          Issue Type: Bug
          Components: core
    Affects Versions: 3.6.8
         Environment: Ubuntu Linux 11.04 x64, JDK 1.6
            Reporter: Vladimir Tsichevski


The following Exception occurs:

  Caused by: java.lang.ClassCastException: ClassX_$$_javassist_129 cannot be cast to javassist.util.proxy.ProxyObject

at the following line

  ( ( ProxyObject ) proxy ).setHandler( instance );

where ClassX is a persistent entity with @ManyToOne references of type FetchType.LAZY. The error was not occurred until the FetchType.LAZY modifier was added.
