Ideally the false positives would get fixed but irrespective of that I
don't mind the other fixes but this one I am less keen on.
Unfortunately, I can't see a better way of fixing it. I thought about
silencing the warning but that has to be at the method level and could
silence a genuine leak in a future commit. Overall this seemed like the
least bad option to get back to zero IDE errors.
And I do find zero IDE errors helpful as it means as soon as I see a
warning I know I've done something wring and can fix it.
