Running `jshell` with `comint-run`.

[Narendra Joshi]

Hi,

Running the Java shell, `jshell`, using `comint-run` hangs after
entering the first input line.

--8<---------------cut here---------------start------------->8---
|  Welcome to JShell -- Version 11.0.7
|  For an introduction type: /help intro

jshell> System.out.println("testing")

<--- hangs forever --->
--8<---------------cut here---------------end--------------->8---

What could be the reason for this? `process-connection-type` has the
default value of `t` so `jshell` is being talked to using a pseudo
terminal. I have tried `jshell` inside `eshell` and I faced the same
issue. It seems to work fine inside `term`.

Can someone help me understand what is going on here?

Best,
