True JavaScript to Java communications

What would the interest be in a JavaScript to Java system that can create and use Java components?

Example

var f = create("javax.swing.JFrame"),

b = create("javax.swing.JButton"),

u = create("X44.events.Uplink");

f.getContentPane().add(b);

b.addActionListener(u);

u.actionPerformed = function _(){import("java.lang.System").exit(0);};

f.exit = function _(){returntrue;};

f.setSize(300, 50);

f.show();
