Hi Eric,
I now dropped these lines:
Options.v().set_whole_program(true);
Options.v().set_app(true);
Scene.v().setMainClass(appclass);
And the number of analyzed packages indeed decreased. But then I get the following error:
Exception in thread "main" java.lang.RuntimeException: This operation requires resolving level SIGNATURES but java.lang.Thread is at resolving level HIERARCHY
If you are extending Soot, try to add the following call before calling soot.Main.main(..):
Scene.v().addBasicClass(java.lang.Thread,SIGNATURES);
Otherwise, try whole-program mode (-w).
at soot.SootClass.checkLevel(SootClass.java:121)
at soot.SootClass.declaresMethod(SootClass.java:326)
at soot.Scene.grabMethod(Scene.java:348)
at soot.Scene.getMethod(Scene.java:368)
at soottest.CalculatorTransformer$MyInstrumenter.addMethodAccept(CalculatorTransformer.java:229)
at soottest.CalculatorTransformer$MyInstrumenter.internalTransform(CalculatorTransformer.java:137)
at soot.BodyTransformer.transform(BodyTransformer.java:51)
at soot.Transform.apply(Transform.java:104)
at soot.BodyPack.internalApply(BodyPack.java:49)
at soot.Pack.apply(Pack.java:124)
at soot.PackManager.runBodyPacks(PackManager.java:774)
at soot.PackManager.runBodyPacks(PackManager.java:454)
at soot.PackManager.runBodyPacks(PackManager.java:373)
at soot.PackManager.runPacks(PackManager.java:350)
at soot.Main.run(Main.java:198)
at soot.Main.main(Main.java:141)
at soottest.CalculatorTransformer.main(CalculatorTransformer.java:118)
The error is because I am creating a static reference as follows:
String methodSig1 ="<" + "java.lang.Thread" +": java.lang.Thread currentThread()>";
SootMethodRef mr1 = Scene.v().getMethod(methodSig1).makeRef();
Value invokeCurrentThread = Jimple.v().newStaticInvokeExpr(mr1);
So, this means that I should still use whole-program mode?
Otherwise, how can I add those SIGNATURES?
Thank you,
Nuno
