You were right, I missed it up.

Here is a patch that turns all methods into abstract methods.

Unfortunately, I could not make Finalize abstract, the compiler
complained that abstract methods must be visible (Finalize is in the
private section). This restriction seems strange to me, but I am not
going to argue with the compiler and left the function generating an
exception at run-time.

I suspect Finalize doesn't need to be abstract, but didn't go
exploring enough to verify why it is abstract.

Also, I noticed that the pointers are "access all". I couldn't see any
requirement for "all", and my code still compiles, so I changed them
to "access". This eliminates a potential source of errors.
