To override this, you can modify the Gatekeeper's default settings to App Store and identified developers from Settings , General , and Allow apps downloads from section. To create a Java application that will start without interruption under the default Gatekeeper settings, the app must be bundled with a JRE, use Oracle's launcher stub, and be signed with an Apple Developer ID.
