• I found a bug, not just asking a question, which should be created in GitHub Discussions.

• I have searched the GitHub Issues and GitHub Discussions of this repository and believe that this is not a duplicate.

• I have confirmed that this bug belongs to the current repository, not other repositories of RocketMQ.

Describe the Bug

I run the unit test of our local branch, but found that the test can't be finished after all test passed.
After a long time of debugging step by step, I found this.

} catch (Exception e) {
       log.error("IndexStoreService force upload error", e);
       throw new RuntimeException(e);
} finally {
       readWriteLock.writeLock().lock();
}

I would call it a typo rather than a bug.

Why didn't we find it early? Is there any tool to help? Sonar plugin or Github Copilot?

As a rule based static code analysis tool, SonarLint failed to find this bug. I've not aware of SonarCloud and SonarQube, since I didn't try them. The java rule set can be found here

What's more interesting and exciting is, LLMs seem to solve this easily. I've tried several of them, result like this:
