I didn't get the "previous version"..I just added a delay between the UI creation and test start.
Earlier also, init is called to do UI creation and then start is immediately called which sets 

inactiveFrame.setVisible(true);
        activeFrame.setVisible(true);

All the semaphore logic is still the same after that
