Hello Steinar. I am usually not involved in Maven Exec development or even use it a lot, but I happen to be the person who implemented the 'blockSystemExit' feature as a PR about 1.5 years ago. So, you may call me an interested party.
A quick test shows that the feature still seems to work as expected up to JDK 24 [1]. What do you mean by "Maven build abrubtly terminates"? The build should terminate with an error, if System.exit was called with a non-zero return code [2] and reported as follows: System::exit was called with return code 123 But that is just Maven Exec failing the build. The JVM should not terminate without notice in the middle of the Mojo execution like without using 'blockSystemExit'. As your gist does not qualify as a reproducer, because I cannot just download and execute it without errors out of context, would you please create a stand-alone reproducer on GitHub and link to it from this thread? The maintainers and maybe I can then take a closer look.
