Apache Dubbo Component

Java SDK (apache/dubbo)

Dubbo Version

openjdk: 1.8 dubbo: 3.2.0

Steps to reproduce this issue

Because Dubbo for Spring Boot starts to destroy itself immediately after receiving the ContextClosedEvent, while the Spring Boot scheduled task (ThreadPoolTaskScheduler) is destroyed later during the DisposableBean.destroy() phase, the destruction order becomes inconsistent.

As a result, Dubbo is destroyed before the scheduled tasks are stopped. If those tasks continue to invoke Dubbo remote services during this period, they will throw the following error:

org.apache.dubbo.rpc.RpcException: Directory of type RegistryDirectory already destroyed for service

What you expected to happen

Research direction
The issue identifies a race condition where Dubbo destroys itself on ContextClosedEvent before scheduled tasks stop, causing RpcException. Investigate the shutdown hook order in dubbo spring boot integration. Look at RegistryDirectory's destroy logic and the Spring context lifecycle to ensure Dubbo shuts down after ThreadPoolTaskScheduler. The assignee's comments may provide additional context.
