:wq in JShell

[Claus Atzenbeck]

Hi all:

I started using JShell for teaching purposes. My default editor is Vim.

JShell's "/edit" command permits me to edit code snippets in Vim directly. After save & quit the updated snippet then returns to JShell.

However, I experience a strange behavior:

:w
:q
Updates the code in JShell (as expected)

:wq
Does *not* update the code in JShell

Is there any guess why :wq does not behave like :w :q?

I'm running Vim 8.0 and Java 11 on Ubuntu Linux.

Best,
Claus
