No, I'm afraid it goes beyond my field of expertise.
It seems to me that the issue is that java is taking for ever to tell 
scilab to call the callback function after you pressed the button.
I don't see how you can catch it using "callback","tic();myfunction()"as 
for me I think the time-line is like:

[Java] ButtonHasBeenReleased ... wait forever for unknown reason ... oh, 
by the way, I'm supposed to register that the ButtonHasBeenReleased 
[Java] > [Scilab] ButtonHasBeenReleased, I call  "tic();myfunction()" 
[Scilab].

I think you need a way to measure this delay for within Java. I am not 
sure you can do it from within Scilab.

Sorry I cannot help more,

Antoine
