If I do remove these lines---I am running ant from the command line--- I cannot run the test at all, so I do need them. This is what I get for removing them:

Here is an overview of the issue:
---------------------------------------------------------------------
        Key: HB-506
    Summary: Non-deterministic? failure of generated proxies
       Type: Bug

     Status: Closed
   Priority: Major
 Resolution: REJECTED

    Project: Hibernate2
   Fix Fors:
             2.1 rc1
   Versions:
             2.0.3

   Assignee: 
   Reporter: Panagiotis Louridas

    Created: Fri, 28 Nov 2003 3:59 AM
    Updated: Fri, 28 Nov 2003 7:24 AM
Environment: redhat linux 9, j2se 1.4.2 (build 1.4.2-b28), postgres, hibernate 2.0.3

Description:
Suppose we have a class hierarchy A <- B, A <- C. Both class B and C have a method getX(). Suppose, moreover, that we have a class R that contains a reference to A.

If we do a query on class R and then a query on class B or C, we *sometimes* get a ClassCastException for the generated proxy when we try to call getX(). In my environment, the same test case succeeds or fails upon repeated execution.
