> It would make debugging Flink errors easier if we would intercept and log calls to System.exit() through the SecurityManager.
> A user recently had an error where the JobManager was shutting down because of a System.exit() in the user code: https://lists.apache.org/thread.html/b28dabcf3068d489f38399c456c80d48569fcdf74b15f8bb95d532d0%40%3Cuser.flink.apache.org%3E
> If I remember correctly, we had such issues before.
