Invocation of System.exit() terminates the JVM, consequently terminating all programs and threads running thereon. This can result in denial-of-service attacks. For example, a call to System.exit() that is embedded in JSP code can cause a web server to terminate, preventing further service for users. Programs must prevent both inadvertent and malicious calls to System.exit(). Additionally, programs should perform necessary clean-up actions when forcibly terminated (via ctrl + c or the for example, by using the Windows Task Manager, POSIX kill command, for exampleor other mechanism).
