lr.join() is lr.wait() behind the scenes but with a check for isAlive(). 
So this suggests you have been getting spurious wakeups from lr.wait() - 
which is theoretically possible but extremely unlikely. If you have the 
cycles could you run the original code with this change:

    lr.wait();
+  if (lr.isAlive()) throw new Error("Spurious wakeup!");

Thanks,
