When you say "native menu bar" I presume you mean the JavaFX SystemMenuBar feature, right?

This is what I expected, and answers question 1: the OpenURIHandler feature doesn't work when JavaFX is initialized first and AWT is running embedded.

This doesn't answer question 2, which was _how_ this fixes the problem. As I said above: "In the case where AWT is running embedded, the `[ApplicationDelegate init]` receiver never gets called." So the code you moved / added in `ApplicationDelegate::init` shouldn't ever be executed in the case you are trying to make work. So I don't understand how this PR, which is the AWT portion of the fix, can possibly make any difference in the failing case. That's why I provided the debug patch and asked if you could do a test run, adding the log output as a comment or attachment.
