> This PR removes the usage of AppContext from the GraphicsDevice class. The > original use case was to store the full-screen window in some AppContext, > which was necessary in the context of plugin/appletviewer environments. > However, there is now effectively only one main AppContext, so this > indirection can be eliminated. > > Notes: GraphicsDevice provides two methods for handling full-screen windows: > - setFullScreenWindow() is considered thread-safe, as all platform-specific > implementations override it with synchronized methods > ([example](https://github.com/openjdk/jdk/blob/23e1e2ff4a4a75ec268c7925fb98d6b96a01bbcf/src/java.desktop/macosx/classes/sun/awt/CGraphicsDevice.java#L226)). > - getFullScreenWindow() previously relied on AppContext for thread-safety. > After removing AppContext, this method is now made thread-safe by declaring > the fullScreenWindow field as volatile. This change has been validated by an > added test.
