> This PR proposes to change the specification for some methods that take `long` offsets so that they will throw an `IllegalArgumentException` rather than an `IndexOutOfBoundsException` for negative values.
> 
> The PR also proposes to fix a bug where the allocation size would overflow and the specified exception was not thrown.
