System.exit behaviour will not be supported from JDK 18+

[ashleyfrieze]

The Security Manager will be removed in later Java and this will stop the SystemExit mocking from working.

Hello, is there any plan to fix this ?

[ashleyfrieze]

If you would like to create a PR then please do. I'll look at it in the mid to long term otherwise.

[ashleyfrieze]

I think the best thing to do is look at a System Stubs v3 for JDK 18+. One that's built on JDK 17 - perhaps keeping the JDK8 branch alive just in case.

[zordym]

Indeed is one of my idea was moving to jdk 17 as most of framework have move on this version

I have fork the project to perform the changes

[ashleyfrieze]

Sounds good @zordym. If you can put up a PR with your best attempt, even if it doesn't work 100%, I don't mind joining in with you on it to try to get it over the line.

Keep me posted on this issue.

[zordym]

For sure, I will do my best

[ashleyfrieze]

@zordym - let's also make sure to update https://github.com/webcompere/system-stubs/blob/main/History.md to include your contribution as well as having you on the usual GH statistics. We do open source because we care about having the tool and sharing that. We deserve the credit.

As far as I understand it's expected behavior, don't I?

@vitalijr2 - yes. You're stubbing System.exit in a later version of Java using System Stubs?

If enough people need a solution to this, we may have to look at a new way of intercepting it from Java 18 onwards.
