Oxygen XML Developer plugin Takes Several Minutes to Start on Mac

If Oxygen XML Developer plugin takes several minutes to start, the Java framework installed on the Mac may have a problem. One solution for this is to update Java to the latest version: go to Apple symbol > Software Update. After it finishes to check for updates, click Show Details, select the Java Update (if one is available) and click Install. If no Java updates are available, reset the Java preferences to their defaults. Start Applications > Utilities > Java Preferences and click Restore Defaults.
