Actually this passes even with src/main/ from this PR and pom.xml from master, i.e. using the original inherited AbstractItem.delete implementation which already cancelled builds and queue items for folder children. It would not call FreeStyleProject.delete prior to Folder.delete but there was not much practical impact (perhaps only missing calls to ItemListener.fireOnDeleted) since all of $JENKINS_HOME/jobs/d/ was deleted.
