The set of preferences that is reported by a platform is hard-coded in the native platform implementation, and depends on the operating system version. It might indeed be the case that an OS upgrade/downgrade could result in a different set of reported properties, but can this happen while a JavaFX applications remains running? In any case, even if that were to happen, the current behavior is that a preference that was once reported will not be removed. ------------- PR Review Comment: https://git.openjdk.org/jfx/pull/1014#discussion_r1316515253
