I'm sure Tom is right about -u, but then we would need an explicit list 
of resource to include. So this is kinda the lazy way.

-static-libgcj is that people who are using it _want_ to include only 
what is necessary, so a 'whole-archive' link of all the properties in 
the .spec wouldn't have made it very far into trunk. Unfortunately for 
you, your platform does only -static-libgcj.
So here's your recipe:
#copy libgcj to a working dir (could be in a different location than 
/usr/lib/ for you)
mkdir -p /tmp/mess_with_libgcj
cd /tmp/mess_with_libgcj
cp /usr/lib/libgcj.a .
#extract all the object from this library
ar x libgcj.a
#make a lib with only the properties objects
ar rvcs libgcj_properties.a *properties*.o
#do the (sometimes superfluous) blessing of the lib
ranlib libgcj_properties.a
#copy the lib to the system lib dir
cp libgcj_properties.a /usr/lib/
#goto your source project and this time link-in those properties objects 
with --whole-archive, this forces the linker to include them even if 
they aren't statically referenced
cd <your source build-tree>
gcj -o <your prog> -Wl,--whole-archive -lgcj_properties 
-Wl,--no-whole-archive -static-libgcj --main=<your main>
