PlatformUI.getWorkbench().getProgressService().run(true, false, runnable) fails to report progress

[kklesatschke]

@fedejeanne and @iloveeclipse we upgraded our product from 2022-06 to 2026-03 and wondered why some of our modal operations don't raise a progress dialog anymore. After some debugging, trial and error I found that busyCursorWhile behaves like we expect.

If this if (!fork || !cancelable) branch shall preserve old (Backward compatible) behaviour, why was it changed to be not backward compatible? Do I need to search through all release notes since 2022-06 or do you have an explanation? 😉

Please note that I am not sure if this is a bug. Could be that we used legacy API in way that is not desired anymore. So please let us discuss.

PlatformUI.getWorkbench()
  .getProgressService().run(true, false, monitor ->{
    //do something long enough to show the progress dialog
    }
 });

@kklesatschke thank you for the report. I am still missing the steps to reproduce but I assume this is what you meant?

• Only set dialog.setOpenOnRun(false) according to preference #486 #4124

Kindly test and report back or add steps to reproduce so that I can validate the PR.
