   @entlicher this breaks the visualization of the debugging state in the IDE (and maybe other things not directly observable). I bisected the visual issue shown below to this commit.
   
   Consider this simple programm:
   
   ### Problem
   
   ```java
   public class Main {
       public static void main(String[] args) {
           System.out.println("Line 1");
           System.out.println("Line 2");
           System.out.println("Line 3");
           System.out.println("Line 4");
       }   
   }
   ```
   
   I have a line break point on the line with "Line 2" in it. I exect the IDE to highlight that line when the break point is hit. I then expect the highlighting to move when I single step through the execution. This does not work anymore. With this merged:
   
   Breakpoint hit:

   ### How it should look

   Please have another look at this.
