Debug Console in VS Code with Java support erroneously splits lines in output for sysout.printf/format

[vitrums]

The question is already on stackoverflow: https://stackoverflow.com/questions/55588019/debug-console-in-vs-code-with-java-support-erroneously-splits-lines-in-output-fo. However this looks more like an issue with RedHat's language support for Java and therefore the question might as well belong here.

Basically System.out.format() and System.out.printf() split lines in unexpected positions and also treat %n inconsistently. From run to run it produces different results. Therefore notice, that the Current Result provided here is just one of many possible random outcomes.

Environment

• Operating System: Windows 10 x64
• JDK version: 1.8.0_181
• Visual Studio Code version: 1.33.0 (user setup)

Steps To Reproduce

1. Create a file PrintfTest.java and open it with VS Code
2. Run

PrintfTest.java:
import java.util.stream.IntStream;

public class PrintfTest {
public static void main(String[] args) {
IntStream.range(0, 10).forEach(it ->
System.out.format("This is iteration %d. Hello VS Code! Hello RedHat!%n", it));
}
}

Current Result

This is iteration
0. Hello VS Code! Hello RedHat!
This is iteration 1. Hello VS Code! Hello RedHat!
This is iteration 2. Hello VS Code! Hello RedHat!
This is iteration 3. Hello VS Code! Hello RedHat!
This is iteration
4. Hello VS Code! Hello RedHat!
This is iteration
5
. Hello VS Code! Hello RedHat!
This is iteration
6. Hello VS Code! Hello RedHat!
This is iteration
6. Hello VS Code! Hello RedHat!
This is iteration
7
. Hello VS Code! Hello RedHat!
This is iteration 8. Hello VS Code! Hello RedHat!
This is iteration
9. Hello VS Code! Hello RedHat!

Expected Result

Just 10 solid lines like in any observable terminal or IDE's console?
