# Class NoExitSecurityManager

java.lang.Object
java.lang.SecurityManager
org.apache.tools.ant.util.optional.NoExitSecurityManager

public class NoExitSecurityManager extends SecurityManager
This is intended as a replacement for the default system manager. The goal is to intercept System.exit calls and make it throw an exception instead so that a System.exit in a task does not fully terminate Ant.

This class is no longer supported in Java runtime versions 18 and higher.
