EXIT_ON_CLOSE as he says is generally frowned upon because it executes System.exit(0) and forces the application JVM to instantly terminate.
If you dispose instead, manually calling dispose() like I do or setting DISPOSE_ON_CLOSE, it allows the JVM to run cleanup.  It also allows you to run multiple windows or applications in a single JVM.
Normally the only time an application should call System.exit() is with a nonzero value for a critical error (crash).  It's like if dispose is telling Windows to shut down, exit() is pressing the power button.
