内存泄漏

Question

Timer timer = new HashedWheelTimer(); 
        bootstrap = new ServerBootstrap(new NioServerSocketChannelFactory(
                Executors.newCachedThreadPool(),
                Executors.newCachedThreadPool()));
        bootstrap.setPipelineFactory(new PortNettyFactory(timer,port));
        bootstrap.setOption("child.tcpNoDelay", true);
        bootstrap.setOption("child.keepAlive", true);
        bootstrap.bind(new InetSocketAddress(port));

我在Jprofiler中使用netty显示内存泄漏。请向我推荐，谢谢！
