Before you can load any custom classes, you first need to load the basic ones using Scene.v().loadNecessaryClasses(). Additionally, force-resolving classes is not the preferred way to make sure that a class gets loaded. If you want to do it all manually (see below for a better way), you should use Scene.v().addBasicClass(…) before you call Scene.v().loadNecessaryClasses().<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>If you just need a unit graph, it might be easier to simply register a transformer and then all Soot’s main method which will perform the required initializations for you.
