The overweight issue resurfaced in June when Lockheed Martin finally
completed the full PDR after an extensive nose-to-tail structural
rework to deal with the fact that the airframe was actually going to
be a massive 35 per cent heavier than estimated.

That says to me that the weight issue was identified and corrected. Note
that is says that the airframe "was" going to be overweight.

It goes on to say that the F-35's weight will be reduced a further 700 to 800
pounds.

Not a problem.
