> 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.
> CI evidence: [run 28625549853|https://github.com/apache/camel/actions/runs/28625549853], job build (25, false).
> Fix: [PR #24403|https://github.com/apache/camel/pull/24403]
