Is there a way to hook / listen to "Problem Occurred" dialog opening?

Context

In our plug-in we try catch a lot of different exception and log them and monitor them. We currently cannot catch, log and monitor unhandled exceptions for which the Eclipse IDE would raise the infamous "Problem Occourred" (ErrorDialog).

In this case I threw an unhandled IllegalStateException to force this dialog to show up.

At best we would like to contribute a handler / hook into it to see if it was an exception somewhere triggered in our plug-in.

Question

Is there a way to implement a specific listener or an extension point for this? Of course at best not to await a shell opening with "Problem Occurred" in the title but I was thinking in the actual Eclipse platform logic that is running before finally opening this dialog. I looked through the code base but could not find anything yet. There is THIS I stumbled upon but I'm not certain if this might be vaild.

On the other hand looking at the dialog with the Plug-in Selection Spy did not yield any result:

It is valid. You have to contribute status handler. I don't have the code at hand right now, but we do this for tests AFAIK.

Thank you very much!

I will have a look myself and will only be back if I don't know how to implement it - or if it is not working 😆

I found the solution, I implemented myself a listener based on org.eclipse.ui.statushandlers.StatusManager.INotificationListener and added it via org.eclipse.ui.statushandlers.StatusManager#addListener(org.eclipse.ui.statushandlers.StatusManager.INotificationListener).
And then filtered a bit to only react to IStatus.ERROR severity etc.

I noticed that this does not seem to work in all cases, e.g. unhandled exceptions in a command handler for example. But I did not find any other issues with that yet - so this is the solution I will go with.

unhandled exceptions in a command handler for example

If you identify some places in Platform where ErrorDialog or MessageDialog is used directly in place of the StatusManager, please submit pull request to make sure the recommended API is used instead; it would most likely fix your cases too.
