This issue is the second part of Borland's mail that originally
reported the issue with access to locals when a class is redefined
- see 4777868.

If a redefined class contains an instance method that is final then any
subsequent calls to the method will continue to execute the <obsolete> implementation. The issue arises because final methods are statically
bound to avoid a vtable dispatch.
