Research direction
Investigate the flaky test PulsarFunctionsJavaProcessTest.testJavaExclamationFunction which fails with a timeout in getFunctionStatus. Examine the test logic in PulsarFunctionsTest.java (line 727 and 1095) to understand the assertion. Look for race conditions or insufficient wait time. Consider increasing the timeout or adding retries. Check if the test depends on external resources that may be slow.
