Method Detail

restartApp

public static void restartApp()

Restart the java application by registering a shutdown hook at the very end of the life cycle. Tested under JRE 8 Windows 10.

This method should be used with caution and testing is needed to be done before relying on it's functionality!. JVM specific security managers, and overall behaviour might impact this method

This method "injects" it's own runnable at the very end of the lifetime of the program after all shutdown hooks have been executed by accessing non private methods via reflection. This might break if the implementation of java will change therefore again be cautious! Guard yourself against constant restarting due to uninitialized conditions.
