problem with WTK

[Anton Stekanov]

When I run some wtk project(Demos for example) in ktoolbar, I get 
following output on its console:
(full log is placed in attachment)

The Demos application nevertheless work.

I can't understand what it mean(
How I can get more intelligible description of this errors?
Is try/catch lines conserned with "Failed to initialize WMA/Bluetooth" 
errors?

I use sun-wtk-2.2_3.
