I don't yet know whether there is an alternative that would allow the menubar to work without deactivating the app, but I filed a follow-up bug to track this:

[JDK-8257835](https://bugs.openjdk.java.net/browse/JDK-8257835): Brief flash in terminal window when launching FX app on macOS

It seems like it might be possible to fix this, since AWT initialization doesn't run into this. I note that AWT uses an Apple-provided "JavaRuntime Support" (JRS) Framework. We would need to see whether there is something else possible using public macOS  APIs.
