Hello, I'm uncertain how to speak to CLI tools and Java games launched from a macOS app. These sound like security and sandboxing questions which we recommend you ask about in those sections of the forums. For games, I've heard of architectures where a parent app launches mini-games built with a 3rd-party game engine. So that at least is possible. In this case it sounds like the launcher app creates a new window via Java and this seems unlikely to work i.e. Game Mode won't migrate to the new window. Game Mode is fully supported for conventional full-screen games such as those you'd build with Metal or RealityKit.
