How do I prove that javaObjectEDT and javaMethodEDT are indeed being run on EDT?

I'm developing a MATLAB-generated Java Package that is to be used in a Java GUI. I want to be sure that when I interact with Swing components, it's being done on the EDT. However, the documentation for javaObjectEDT and javaMethodEDT is pretty sparse. When I run the following code, it tells me that the current thread is 'main' instead of 'AWT-EventQueue-0' like I expect. Am I using this incorrectly? How do I ensure that Java objects and methods are being run on the EDT?

import java.lang.Thread

javaMethodEDT('getName',Thread.currentThread)

Your invocation of Thread.currentThread is executed in the matlab main thread not on EDT.

Do as follows.

t = javaMethodEDT('currentThread','java.lang.Thread');
t.getName
%ans =
%AWT-EventQueue-0
