That didn't answer all my questions, at least not in a way that I can understand.

How is this useful given that we disable jtreg failure handlers for the headful tests ?

It definitely isn't a core-libs change. I think build-dev may be better.

Previous changes to these configs were discussed here, so I have send it here as well.


I am also unclear when this failure handler is invoked and how all this machinery works.

It is only useful for headful tests and so I'd only want it enabled in such a case. And we disable the failure handlers in the headful test jobs anyway because they seem focused on taking pointless core dumps ...> So we need something that can be used with headful tests only and doesn't involve
re-enabling the other handlers.
It could be useful for other tests as well and may be able to identify problems such as:
 - Suggestions "to open under debugger" from the native asserts
 - Various error dialogs from the OS
And it does not spend much resources compared to current handlers.


Also why exclude Windows ? No easy way to get the screenshot ?

There is no command-line program that can take a screenshot on windows by default

Hello.
Please review the fix for JDK 14.

Bug: https://bugs.openjdk.java.net/browse/JDK-8233827
Fix: http://cr.openjdk.java.net/~serb/8233827/webrev.01

This change adds the "screen capture on the test failure" feature on macOS and Linux. - On Linux, it is implemented by the "gnome-screenshot" command(in case of multiscreen+xinerama the whole big screen will be saved to the "screen.png" file). - On macOS it is implemented by the "screencapture" command, note that I have used 1 file per screen, if the number of screens less than 5, other files will be ignored.
