Dev mode captures console input destined to the application

[PierreBtz]

Describe the bug

Running an interactive CLI (Quarkus command mode) in Quarkus dev mode (mvn quarkus:dev), Quarkus dev mode partially captures the keystrokes.

Expected behavior

I would expect the dev mode to capture the keystrokes only if the application didn't consume them before. Or if this is not possible, then I would expect a way to configure a modifier key to access the dev mode shortcuts, and the application to get everything when the modifier key is not pressed.

Actual behavior

The pattern I found is that:

• for an input that is part of the dev mode shortcuts (eg h): the keystroke is captured by the dev mode and doesn't go to the application
• for an input that is not part of those shortcuts (eg m): the keystroke goes once to the application and is lost once (so if I type m twice, it appears only once for the application).

How to Reproduce?

Please find a reproducer in https://github.com/PierreBtz/quarkus-termio-bug.

Steps to reproduce:

• Build the project (mvn package).
• Verify that it works properly with the uber-jar, you have two commands:
  java -jar target/quarkus-textio-bug-1.0.0-SNAPSHOT-runner.jar textio and
  java -jar target/quarkus-textio-bug-1.0.0-SNAPSHOT-runner.jar reader reading an input from Console and displaying it.
  One command uses a basic InputStreamReader, the other TextIO (which is
  how I noticed the problem initially...).
• You can also verify it works with a native executable.
• Run mvn quarkus:dev -Dquarkus.args="textio" and observe how part of the inputs are captured by the Quarkus dev mode.
