Description

The following code is faulty:

        ObjectInputStream in = new ObjectInputStream(new BufferedInputStream(
            new FileInputStream(path.toUri().getPath()), 4096));
        try{
          mapJoinTables[pos] = mapJoinTableSerdes[pos].load(in);
        } finally {
          in.close();
        }

If an exception is thrown from any of the stream constructors, then the wrapped stream will not get closed.
