\b behaving weird in IntelliJ's console

Question

I was trying to display a String and then clear it after some time.
The following code is working.

    String hello = "Hello";
    System.out.print(hello);
    int length = hello.length();
    for (int i = 0; i < length; i++)
        System.out.print("\b");

But when I thought to display it for few seconds (Using Thread.sleep(time) ), it is not working (code below). When I was debugging it I noticed that after the first execution of the loop, cursor starts pointing to the next line.
So, Is there any way to display for few seconds and then clear it.

String hello = "Hello";
System.out.print(hello);
int length = hello.length();
Thread.sleep(10);
for (int i = 0; i < length; i++)
    System.out.print("\b");

probably only because it was flushed in one chunk, on which you can't rely. — Meo, Feb 17 '18 at 06:09
This does that, but it is really low level, once that chunk gets printed to the console component, there is no way back, it only appends text https://github.com/JetBrains/intellij-community/blob/daaa6e228ec0418b034db88deee8c8e570c9d46b/platform/platform-api/src/com/intellij/execution/process/AnsiEscapeDecoder.java#L56 — Meo, Feb 17 '18 at 06:13

Regarding the answer, it is not an actual answer. Because answer is really donot use Intellij or eclipse (because it worked in netbeans and command line) – Feb 17 '18 at 07:26
You asked about IntelliJ, this is the best answer you will get. Maybe it will be implemented in the future. – Meo Feb 17 '18 at 07:51
