David,

I am resending my previous email. I have a log file as
an attachment, please let me know how to send this. 

Is it possible for you guys to go and look into the SWT 
archives of the eclipse.org. Thanks!

Mike,

Thanks for the response. Yes, the arguments look reasonable 
enough and I have already gone thru. listing out the <xy> points, 
the drawable, display and the GC with their respective style
and mode, which is the default(Complex & CoordModeOrigin). 
Also, tried with the different combinations of style and mode 
arguments, no change. Created a simple example C program,
which contains the same points as the one in the controlexample 
program, and the XFillPolygon works fine. I have attached the 
controlexample log file where it list out the debug info. of the
JNI code before hanging in XFillPolygon. And also, note that, 
by replacing it with XDrawLines draws the lines on the arrow 
button of the Tab widget and runs the controlexample pgm just fine.

I will go thru. more thoroughly on the HP documentation for 
any hints or specifics for the above problem to occur.

Thanks
-Sri
