---------------------------------------
Summary: Flaky SpringFileWatcherTest.testDefaultConfig on JDK 25
Key: CAMEL-23893
URL: https://issues.apache.org/jira/browse/CAMEL-23893
Project: Camel
Issue Type: Bug
Components: camel-file-watch
Reporter: Guillaume Nodet
SpringFileWatcherTest.testDefaultConfig fails consistently on JDK 25 (3/3
attempts with surefire.rerunFailingTestsCount=2) while passing on JDK 17.
The test expects exactly 2 events (two MODIFY events from two Files.write()
calls) but receives 3 on JDK 25. The root cause is that JDK 25's WatchService
initializes faster and delivers a CREATE event for the file created in
@BeforeEach, producing 3 events total (1 CREATE + 2 MODIFY). Additionally, the
test used Thread.sleep(50) between writes, which is too short for CI and does
not guarantee the file hasher processes the first write before the second.
The fix changes setExpectedCount(2) to expectedMinimumMessageCount(2) to
tolerate the additional CREATE event, replaces Thread.sleep(50) with
Awaitility, and increases the result wait time for CI robustness.
