How? If `DiskItem.write` doesn't throw `Exception` `FooDiskItem.write`
can't.
> My new code obviously does not catch that Exception and it percolates up
the stack.
That's what you want because that's the meaning of a raw `Exception` and
that's why `throws Exception` and `catch(Exception)` is generally a bad idea.
The system works, it just might cause an inconvenience in this situation where
idioms have not been used correctly in the first place. I don't think the
situation is possible, though because `FooDiskItem.write` in 1.4.x can't throw
Exception anymore.
