研究方向

Investigate the flaky test TopicsTest.cleanup by examining the test file TopicsTest.java and the base class MockedPulsarServiceBaseTest. Focus on the stack trace showing a ClassCastException in PulsarService.getConfiguration. The issue suggests a mismatch between the expected type in the test setup. Look at the method stopBroker and internalCleanup to see where the wrong object is being cast. Also check if there are any recent commits that might have introduced this issue. Consider adding more robust mocking or ensuring that the PulsarService is configured with the correct ServiceConfiguration instance.
