When Invocation of System.exit() is invoked, terminates the JVM, consequently terminating all programs and threads running on the JVM terminatethereon. This can result in denial-of-service attacks, for . For example, a web server can stop servicing users upon encountering an untimely call to System.exit() that is embedded in some 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 kill command, for example).
