Mmm... Simple example. Here's my main class.
public class ReadWebPageContents extends UiApplication
public static void main(String  args)
ReadWebPageContents newApp = new ReadWebPageContents();
ReadWebPageContentsScreen readWebPageContentsScreen = new ReadWebPageContentsScreen();
There is a breakpoint on string System.out.println("Start!!!!!");
I start debugger. It stops and points to this string. I press "Step over" button. Pointer moves to the next line. But there is no changes in console. But at the same time in the window with variables appears newApp as the line with creating newApp was execute instead.
