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.

Apparently the weight problem still exists, see:-
http://www.dfw.com/mld/dfw/news/7687756.htm

The Ctol empty weight should be 29000lbs and is currently at approx
31000lbs

Around 7% overweight, and includes the saving from abandoning the
quick mate process (700-800lbs)

Spokesman for LM John Smith said "We don't think we're where we need
to be,"

Pentagon officials decided to budget more money and delay plane orders
because they are concerned that Lockheed will find it even more
difficult to meet weight goals for the Navy and Marine F-35 variants.
