That's good news.

The warning and the 5 second freeze are the same problem. [`MacApplication::waitForReactivation`](https://github.com/openjdk/jfx/blob/5b39c916ba36d9522b9e72dccd4dc8ae5792dae4/modules/javafx.graphics/src/main/java/com/sun/glass/ui/mac/MacApplication.java#L109-L114) waits for up to 5 seconds for the window to be activated. After 5 seconds, it logs the warning and proceeds anyway.

Thanks for confirming. I'll remove the debug prints and make this PR "rfr".
