It seems only be failing on Mac with Java 17

Here are a few of the repo lines

Still failing on macOS with Java 17: https://gradle-enterprise.elastic.co/s/u5yiuehfhwel4/tests/:server:test/org.elasticsearch.watcher.FileWatcherTests/testSimpleFileOperations

Another one: https://gradle-enterprise.elastic.co/s/z4o34g7bqgodk/console-log?task=:server:test

[cbuescher]

Another one today on master, also a Darwin build: https://gradle-enterprise.elastic.co/s/azbqkmlx7arda
Is there any information we need to gather at this point from more failures or can I try doing a platform-specific mute here for now? @probakowski

Another Darwin/master combo failure

https://gradle-enterprise.elastic.co/s/fj3vvouwtcb2c/tests/:server:test/org.elasticsearch.watcher.FileWatcherTests/testSimpleFileOperations?top-execution=1

Also FileWatcherTests::testSimpleDirectoryOperationsWithContentChecking failed with a similar error

java.lang.AssertionError:

  | Expected: iterable with items ["onFileChanged: test-dir/test2.txt"] in any order |  
  | but: no item matches: "onFileChanged: test-dir/test2.txt" in []
