blockSystemExitCalls

public static void blockSystemExitCalls()

Blocks System.exit() calls from exiting the JVM and instead throws a SecurityException in its place. This is useful when running a JVM through an interactive interpreter such as Python so that individual commands to not cause the REPL to exit. This will generate a WARNING message in Java 17, and must be explicitly allowed in future JDK releases.
