This issue is reproducible with latest build. Compilation would succeed if the user do a clean build and rebuild. But if the user run the app then it throws same Exception.So workaround for this issue is delete the notifications-1.0.1-sources.jar file from lib directory. Exception would not occur both compile time and run time. notifications-1.0.1-sources.jar fie does not used anywhere
