The exit permission is not granted by default to applets. This is
because all applets that are running in the browser share a single JVM.
If one applet calls System.exit(), all applets will die. This is
something we do not want, so we don't grant that permission.
For javaws, the security manager handles this permission like any other,
allowing sufficiently privileged applications to override it.
