The use of java.lang.Runnable in SwingUtilities.invokeLater(Runnable obj) is
misleading. It lead me to infer that the run() method of the Runnable is called
in a new thread launched by the AWT-dispatcher thread. If the intention was to have an interface with a well known method with no parameters - might as well
define a new interface

public interface com.sun.java.swing.LaterInvokable()
{
public void nowDoit();
}

Somehow the Runnable interface is strongly associated with the java threading
in my and other java programmer's mind's.

Here is what the javadoc for Runnable says -

The Runnable interface should be implemented by any class whose instances are intended to be executed by a thread. The class must
define a method of no arguments called run.

This interface is designed to provide a common protocol for objects that wish to execute code while they are active. For example,
Runnable is implemented by class Thread. Being active simply means that a thread has been started and has not yet been stopped.
