A project used to reproduce rlwrap issue #98

The issue: hanslub42/rlwrap#98

Prerequisite

You need setup the following software packages to run the demo project:

1. JDK 1.7 or 1.8
2. Maven 3.6.x

Reproduce steps:

1. Clone or download this repo
2. Open console window, enter the project folder and type mvn clean compile act:run
3. Open another console window, type rlwrap nc localhost 5461
4. Then type bar

You can see the bar will cause the screen scroll up.

If you use nc localhost 5461 without rlwrap in step 3, then the screen will not scroll up.
