Upgraded to SonarQube 7.7 and the embedded Restart within the UI fails on the backend. Install base is Windows 2016 and SonarQube installed as a service. The service stops, fails to complete the cleanup and thus fails to restart. Have to manually start the service again to get SonarQube up and running again. New es6 directory and files created with each startup, so not a one-time legacy file cleanup that would resolve the issue. Full log below showing the entire process.
