Save a source file with a method containing an inner block (eg. for loop):

public class NewClass {
  public static void main(String[] args) {
    {
      
    }
  }
}

Now, add a comment in the line of the closing bracket.

public class NewClass {
  public static void main(String[] args) {
    {
      
    } // Whatever
  }
}

Using the the History/Remove function will incorrectly remove the whole line, including the closing bracket.

public class NewClass {
  public static void main(String[] args) {
    {
      
  }
}
