I'm using librairies included in the swingwt debian package and I 
suppose that the -fjni flag is set.
I also tried to compile swingwt 0.85 myself (I verified the Makefile and 
the -fjni flag is set) to get
libswt compiled with -fjni. Unfortunately, libswt is linked with 
libswt-mozilla-gtk-3063.so that contains unresolved symbols:
/tmp/SwingWT/lib/linux_gtk2/libswt-mozilla-gtk-3063.so: undefined 
reference to `nsCString::nsCString[in-charge]()'
/tmp/SwingWT/lib/linux_gtk2/libswt-mozilla-gtk-3063.so: undefined 
reference to `vtable for nsQueryInterface'
/tmp/SwingWT/lib/linux_gtk2/libswt-mozilla-gtk-3063.so: undefined

/tmp/SwingWT/lib/linux_gtk2/libswt-mozilla-gtk-3063.so: undefined 
reference to `nsString::nsString[in-charge]()'
I didn't set the LD_LIBRARY_PATH. At All, I don't have any errors or 
warnings

Here is an example of the execution with a System.out.println("Hello"); 
added just after shell.open();:

hostname:/home/me/projects/GUISWT# ./Test
Hello

and that's all... I got no errors or warnings at the compilation or 
execution steps, that's why I really don't understand...

I'm using:
gcj both 3.4 & 3.3
libgcj4 required by libswt.so
