Since "Provider" is capitalized, I think the intent was that this was the classname, so it should also probably be in an `@code` tag. Alternatively, you could change this to non-capitalized "provider" (w/o the @code tag) and I think it would still be readable (and my vote would be for this).

Since `Provider` here is a parameter, it is probably better to put this in an `@code` tag.

Integer.MAX_VALUE should be inside a `@code` tag.
