The causes of a CompositeIoException are lost when the exception is rethrown as part of a chain, (ie it is a cause in another Throwable).
This is because Throwable.printStackTrace() does not call printStackTrace on its causes but rather printEnclosedStackTrace to handle circular references and prevent a thread loop.
This is exceptionally painful when upgrading to 2.204 for the most recent LTS as something in that chain causes tests to fail if the temporary JenkinsHome of a JenkinsRule Test can not be cleans.
it results in failures like:

This is exceptionally painful on windows where you can not delete a directory if the same process has files open in it, and when the failure is on a CI system and the developers all have Linux/Mac then it becomes even harder.
without knowing which file(s) could not be deleted you are effectively fishing. You can inspect the exception if you are lucky enough to trap it locally to obtain the info, but this is unlikely to happen for a running Jenkins instance or a test running in CI.
