You need an update that isn’t on the main Oxygen site. Add http://download.eclipse.org/webtools/repository/oxygen/ as a URL in your Available Software Sites preference page and then check for updates from the Help menu. https://bugs.eclipse.org/533162 Edit: this fix will be properly included in the Photon (WTP 3.10) release later this month.
