So I found a workaround, though I don't understand the why of the problem or
workaround.
What I found was that on MacOSX 7u25+, my app mainSwing() (executed via
invokeLater() from main()) was being called on AWT-EventQueue-2 from the JAWS
startup thread (javawsApplicationMain) instead of AWT-EventQueue-0. So I added
code to force JavaFX init, switch over to the FX thread, and switch back to
Swing, which is then AWT-EventQueue-0:
if(Thread.currentThread().getName().equals("AWT-EventQueue-2")) {
new JFXPanel();
Platform.runLater(new Runnable() { public void run() {
SwingUtilities.invokeLater(new Runnable() { public void
run() {
mainSwing(args); }}); }});
return;
}
And now my JOptionPane correctly blocks events outside of the dialog!
