This is in run() method in Thread:

        while (localStack.keySet().iterator().hasNext()) {
          String fileName=(String)localStack.keySet().iterator().next();
        }

Now, what would happen if somebody else, out of this thread, adds/removes a
few lines in localStack while this loop is running. LocalStack is HashMap.

Thanks for helping !
Peter
