If ObservableList.size() >= 18, Collections#reverse() throws an exception.
If you run the attached test code(ObservableListTestCase.java), you will get the following exception.
testReverseObservableListWith18Elements(org.mule.module.launcher.util.ObservableListTestCase) Time elapsed: 0.012 sec <<< ERROR!

You can find that Collections#reverse is called with an instance of ObservableList<Application> in DeploymentDirectoryWatcher#stopArtifacts.
The attached patch fixes it. It is for 606a08f0381debca529e8fcf2aa963c0a618bb1e on mule-3.x branch.
I can make a pull request, if you want.
