Trouble setting JSlider position

Hello everyone,

I have been playing with jsliders for a while now, and have never had
any trouble positioning sliders where I want in response to particular
events. I am running into trouble right now though, where I want to
prevent one slider from passing below the value of another slider.

I have written a simple program which demonstrates this problem. The
program displays two sliders (only listens to second slider). If I
move the second slider below the first slider and release it,
- it shows the proper portion of code has been reached;
- it shows the lower bound has been read correctly;
- it shows that the value of the slider has been reset properly;
- problem: as soon as the slider value is adjusted by the program, it
goes right back to where the user had set it.

I am guessing the problem is in the checkSliderBounds method, but maybe
it's in the stateChanged method. Any thoughts?
