[Soot-list] Problem in Call graph construction

[Asif Iqbal]

Hi Eric and others,

I am trying to generate call graph for a simple Java class. Below is my code snippet:

        .....

	Scene.v().setSootClassPath(Scene.v().getSootClassPath() + ":" +
                ".:" +
                 "/Developer/Projects/SootCallGraph");
                 System.out.println(Scene.v().getSootClassPath());
        
        SootClass sootClass = Scene.v().loadClassAndSupport("InheritanceTest");

        sootClass.setApplicationClass();
        Scene.v().setMainClass(sootClass);

        CHATransformer.v().transform();

        String [] opts = {"-W", "InheritanceTest" };
        String[] args = {"-f", "X", "InheritanceTest"};

        Main.main(opts);
        //Main.main(args);

	.....

At the line Main.main(opts) I get the following exception:
Exception in thread "main" java.lang.RuntimeException: This operation requires resolving level BODIES but java.lang.Object is at resolving level SIGNATURES
If you are extending Soot, try to add the following call before calling soot.Main.main(..):
Scene.v().addBasicClass(java.lang.Object,BODIES);
Otherwise, try whole-program mode (-w).

Do you have any idea what is causing this ? Note that instead of Main.main(opts) if I use the commented line Main.main(args) then it works and successfully generates the xml. So is there any problem in the whole program mode ?
