Therefore the test is provided in a separate repository and it needs to be discussed if the test is necessary to have inside the JFX repo and if so, how it should be integrated.

We'll need some sort of standalone test, even if it can't be automated, that we can use to test the fix. Something that isn't a full-blown app. The test program should be able to reproduce the problem without the fix and can then be used to verify the fix.

When testing, we will want to consider the following scenarios:

1. Pure JavaFX app (even though there isn't a `java.awt.desktop.OpenURIHandler` in this case, we need to make sure that it doesn't misbehave)
2. JavaFX + Swing app -- JavaFX Toolkit initialized first (I think this is the main case you want to handle)
3. JavaFX + Swing app -- AWT Toolkit initialized first (I presume this case already works, so the main thing is to ensure no regressions)
