Hello Stuart,
My understanding of the the lazy `Holder` is that it's there to delay the
static initialization of the code that's part of the `Holder`. In this case
here, the `Holder` is being used right within the `static` block of the
`Finalizer` class, that too as the first thing. In this case, is that `Holder`
class necessary?
