Hi everyone,

I've written a newsletter with a little concurrency puzzle that you 
might find amusing to try.  It is not difficult to solve, but please 
don't post your solution for now.  The code is very obviously broken, 
but it fails a bit too predictably.  Enough said ...

Once you've found the reason why it fails so consistently, the next step 
is to fix the code using Java 8 StampedLock.

This is just a thought exercise, so please don't go putting this class 
into your code base :-)

Regards

Heinz
