I attach two test cases showing the problem.

ant create-db; ant -Dtest.case=QueryProxyParentChildren test

succeeds, whereas

ant create-db; ant -Dtest.case=QueryProxyChildrenParent test

fails.

Here is an overview of the issue:
---------------------------------------------------------------------
        Key: HB-537
    Summary: Proxy Problem with overloaded functions
       Type: Bug

     Status: Unassigned
   Priority: Major

    Project: Hibernate2
   Versions:
             2.0.3

   Assignee: 
   Reporter: Panagiotis Louridas

    Created: Wed, 10 Dec 2003 5:50 AM
    Updated: Wed, 10 Dec 2003 5:54 AM
Environment: linux, Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2-b28), hibernate 2.0.3, postgres.

Description:
Suppose we have class A and two subclasses A<-B, A<-C. Suppose now that B has methods Foo getFoo() and void setFoo(Foo), while C has methods Bar getFoo() and void setFoo(Bar).

I get strange proxy behaviour when working with objects of classes A, B, C. Specifically, when querying on B, C and then on A, I get 

SEVERE: CGLIB Enhancement failed
java.lang.IllegalArgumentException: Can't implement:
InterestPayment
and
TaxPayment

(where InterestPayment = B and TaxPayment = C).

Everything works fine when querying on A and then on B and C, though.
