Need some help with this tcp proxy

[dEvilKinG7]

Hey, im using this tcp proxy: https://github.com/terma/java-nio-tcp-proxy

but the shut down function doesn't work as it always gives null workers showing "already been shutdown"

https://github.com/terma/java-nio-tc...TcpServer.java

    public void shutdown() {
        if (workers == null) {
            if (LOGGER.isLoggable(Level.INFO))
                LOGGER.info(name + " already been shutdown");
            return;
        }

        if (LOGGER.isLoggable(Level.INFO))
            LOGGER.info("Starting shutdown " + name);

        for (final Thread worker : workers) {
            worker.interrupt();
            try {
                worker.join();
            } catch (InterruptedException exception) {
                Thread.currentThread().interrupt();
            }
        }
        workers = null;

        TcpServerHandler handler;
        while ((handler = handlers.poll()) != null) handler.destroy();
        handlers = null;

        if (LOGGER.isLoggable(Level.INFO))
            LOGGER.info(name + " was shutdown");
    }

could anyone help?
