### Pre-check - [X] I am sure that all the content I provide is in English. ### Search before asking - [X] I had searched in the [issues](https://github.com/apache/dubbo/issues?q=is%3Aissue) and found no similar feature requirement. ### Apache Dubbo Component Java SDK (apache/dubbo) ### Descriptions This is the source code of the ThreadlessExecutor waitAndDrain method: https://github.com/apache/dubbo/blob/ca7151e53166fc69079fefff074ee369aa29f134/dubbo-common/src/main/java/org/apache/dubbo/common/threadpool/ThreadlessExecutor.java#L52-L80 It seems that if waitAndDrain is called twice in a multi-threaded scenario, there will be no wait on the second execution because if the cas fails, it will return. Here is my test code: > @Test > void testV2() throws InterruptedException { > new Thread(()->{ > try { > executor.waitAndDrain(Long.MAX_VALUE); > } catch (InterruptedException e) { > throw new RuntimeException(e); > } > }).start(); > executor.waitAndDrain(Long.MAX_VALUE); > System.out.println("wait not worked"); > } There is no example in Dubbo where waitAndDrain is executed through the same threadlessExecutor across multiple threads, so there shouldn't be any issues. I don't know if this is a bug. ### Related issues _No response_ ### Are you willing to submit a pull request to fix on your own? - [X] Yes I am willing to submit a pull request on my own! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
