在dubbo2.7.5中，如果没有服务提供者的话会抛出“No provider.....”的异常。但是在3.0.10中，如果invokers是空数组的话就会出现数组越界。这个改动是为什么呢？ image

Contributor guide

Research direction
Inspect ZoneAwareClusterInvoker's doInvoke method to trace why empty invokers lead to array index out of bounds instead of throwing a No provider exception. Check the logic for handling empty invoker lists.
