Instrumentation failure, Resolved Field is Null #19

Open amordahl opened 2 years ago

amordahl commented 2 years ago

When trying to run Slicer4J through the python script, the instrumentation fails. I am using JDK 9, on Mac OS. Here is the content of instr-debug.log.

SLF4J: Class path contains multiple SLF4J bindings.

Thank you for submitting the issue. Can you please attach the jar file and the command you used to run the slicer?

amordahl commented 2 years ago

Sure. I am trying to run Slicer4J on FlowDroid; I've attached the jar. The command I used to run is

python slicer4j.py -j ~/git/FlowDroid/soot-infoflow-cmd/target/soot-infoflow-cmd-jar-with-dependencies.jar -b soot/jimple/infoflow/Infoflow:711 -o ~/test -m "soot/jimple/infoflow/cmd/MainClass -a ~/Downloads/DroidBench30/benchmark/apks/Aliasing/FlowSensitivity1.apk -p ~/Library/Android/sdk/platforms -s ~/git/FlowDroid/soot-infoflow-android/SourcesAndSinks.txt "

Hi Khaled, just following up on this issue. Let me know if there's anything else you need. Thanks!

khaled-e-a commented 2 years ago

Hi @amordahl , I am still working on this, I am facing a different issue [Thread-40] ERROR heros.solver.CountingThreadPoolExecutor - Worker thread execution failed: 1 java.lang.ArrayIndexOutOfBoundsException: 1 at org.objectweb.asm.MethodWriter.visitParameterAnnotation(MethodWriter.java:697)

I am currently working on it, but have other projects to work on so the progress maybe slow. May I know are you able to slice other programs? is your work blocked by this issue? Thank you for your patience
