The last three methods in IconSource.c has names that uses IconFactory instead
of IconSource.

JNIEXPORT jint JNICALL Java_org_gnu_gtk_IconFactory_gtk_1icon_1source_1get_1type
(JNIEnv *env, jclass cls)

JNIEXPORT void JNICALL
Java_org_gnu_gtk_IconFactory_gtk_1icon_1source_1set_1icon_1name
(JNIEnv *env, jclass cls, jobject source, jstring icon_name)

JNIEXPORT jstring JNICALL
Java_org_gnu_gtk_IconFactory_gtk_1icon_1source_1get_1icon_1name
(JNIEnv *env, jclass cls, jobject source)

This causes UnsatisfiedLinkErrors when you try to run a program that would
invoke one of these commands.

Test Case:
import org.gnu.gtk.*;

public class Main {
    
    public static void main(String[] args) throws Exception {
        Gtk.init(args);
        IconSource is = new IconSource();
        is.setIconName("gnome-globe");
        IconSet set = new IconSet();
        set.addSource(is);
        Image i = new Image(set, IconSize.BUTTON);
        
        Window w = new Window(WindowType.TOPLEVEL);
        w.add(i);
        w.showAll();
        Gtk.main();
    }
}
