此时Task构造器先被增强,然而因为Task构造时RestStrategyContext尚未加载, 所以DiscoveryServicePlugin对应的ThreadLocalHook还未注册,Object[] objects = ThreadLocalCopier.create(), 此行代码objects结果为空, 灰度结果会异常.
即使这里为空的话,为什么灰度结果会异常呢?

@yanbw 无法重现你说的问题,该测试用例集成在DiscoveryGuide上,经过测试,该问题似乎不存在,你是否可以通过DiscoveryGuide来重新你说的问题?参考https://github.com/Nepxion/DiscoveryGuide/blob/6.x.x/discovery-guide-service/src/main/java/com/nepxion/discovery/guide/service/feign/AFeignImpl.java中
@Override
@SentinelResource(value = "sentinel-resource", blockHandler = "handleBlock", fallback = "handleFallback")
public String invokeThread(@PathVariable(value = "value") String value) {
Runnable runnable = createRunnable(value);
new Thread(runnable).start();
return "Invoke Thread";
}

测试代码如下
启动a、b 1.0版本应用
应用启动后第一次调用(n-d-version = {"discovery-guide-service-b":1.1} )
调用结果
第二次调用
第二次调用结果,调不通(b应用1.1不存在,调不通才是正常结果)

这个问题的确存在。原因是异步的时候, 初始化Agent相关类和业务调用基本同时开始。当业务调用先于Agent初始化完成,那么灰度不会生效。这种情况只会发生在第一次。我们考虑一下,怎么解决

一个非技术角度的观点@yanbw
你的异步调用结果只是打印一句话,而真正生产环境的执行代码相对耗时较长,应该绝大多数情况是Agent初始化代码先执行完毕
