Start with LocalSampleAppIntegrationTest.testSample at lines 95 and 197, then inspect the Awaitility condition for the 'Started PubSubConfigApplication' log message. Reproduce the timeout and determine why startup is not observed reliably; done means the integration test completes without intermittent ConditionTimeoutException failures.
