DoNotCallSystemExit

DoNotCallSystemExit

Web applications should not call System.exit(), since only the web container or the application server should stop the JVM. This rule also checks for the equivalent call Runtime.getRuntime().exit().


//Name[
    starts-with(@Image,'System.exit')
    or
    (starts-with(@Image,'Runtime.getRuntime') and ../../PrimarySuffix[ends-with(@Image,'exit')])
]
    		
Example(s):


    		
public void bar() {
    System.exit(0);                 // never call this when running in an application server!
}
public void foo() {
    Runtime.getRuntime().exit(0);   // never stop the JVM manually, the container will do this.
}
