Exporting images/data to Fiji via the `Export` button hangs on macOS

[elevans]

The user Erosion on the image.sc forum reported that the export function in FLIMJ UI cases the application to hang. See here for the post. So far I have been able to replicate this on an older Intel mac running macOS Sonoma 14.8.3. This issue is not present on Windows or Linux.

This will require some remote debugging.

This issue has been mentioned on Image.sc Forum. There might be relevant details there:

I setup a remote debugging session and traced the bug to here. After obtaining and converting the selected export image/datasets we try to get the current UIService which hangs on macOS.

Edit: Actually it's the show() call after we get the UIService.

A quick progress update. I tracked the bug to some strange JavaFX / SwingUI thread lock bug. It's likely the same issue I ran into earlier when I used JavaFX's openers instead of the swing ones served by the UIService. Unfortunately in this particular case we must interact with UIService to display the images. More debugging is needed...
