SystemExit

Reports calls to System.exit(), Runtime.exit(), and Runtime.halt().

Invoking System.exit() or Runtime.exit() calls the shutdown hooks and terminates the currently running Java virtual machine. Invoking Runtime.halt() forcibly terminates the JVM without causing shutdown hooks to be started. Each of these methods should be used with extreme caution. Calls to these methods make the calling code unportable to most application servers.

Use the option to ignore calls in main methods.
