What is Java module jdk.editpad?

Question

The JDK ships with a module jdk.editpad that exports no services or packages. The Javadoc describes this module as:

Provides the implementation of the edit pad service used by jdk.jshell.

But if you look at the modules depended on by jdk.jshell, jdk.editpad does not appear in the picture.

So what is jdk.editpad, what does it do, and where is it documented?

Answer 1

jdk.editpad is a really small module that provides a simple Swing-based GUI text editor.

Here's the code if you want to see for yourself.
