---------------------------------
Summary: Fix resource cleanup bug in GrpcServicesImpl.closeImpl()
method
Key: RATIS-2406
URL: https://issues.apache.org/jira/browse/RATIS-2406
Project: Ratis
Issue Type: Bug
Reporter: Shilun Fan
Assignee: Shilun Fan
## Description
There is a bug in the `GrpcServicesImpl.closeImpl()` method where
`super.closeImpl()` is called inside the server shutdown loop, leading to:
1. **Multiple invocations**: The parent class cleanup logic is executed
multiple times (once per server)
2. **Resource leak risk**: If any server shutdown fails with an exception,
`super.closeImpl()`, `serverInterceptor.close()`, and
`ConcurrentUtils.shutdownAndWait(executor)` won't be executed
