Exception when scan the timeout invocation of remoting.

[yxxstar]

当dubbo超时请求，一直会刷那个日志不停。。报空指针异常
private static class RemotingInvocationTimeoutScan implements Runnable {

    public void run() {
        while (true) {
            try {
                for (DefaultFuture future : FUTURES.values()) {
                    if (future == null || future.isDone()) {
                        continue;
                    }
                    if (System.currentTimeMillis() - future.getStartTimestamp() > future.getTimeout()) {
                        // create exception response.
                        Response timeoutResponse = new Response(future.getId());
                        // set timeout status.
                        timeoutResponse.setStatus(future.isSent() ? Response.SERVER_TIMEOUT : Response.CLIENT_TIMEOUT);
                        timeoutResponse.setErrorMessage(future.getTimeoutMessage(true));
                        // handle response.
                        DefaultFuture.received(future.getChannel(), timeoutResponse);
                    }
                }
                Thread.sleep(30);
            } catch (Throwable e) {
                logger.error("Exception when scan the timeout invocation of remoting.", e);
            }
        }
    }
}

详细异常堆栈能贴一下吗

[chickenlj]

用的什么版本的dubbo？如果你这找到了详细的堆栈，可以再打开issue
#459 参考下和这个issue有没有关联
