[Soot-list] loadnecessaryclasses error

[Eric Bodden]

Hi Iverson.

I’d recommend NOT calling loadNecessaryClasses(). Instead, after you have set your options, call soot.Main.main(…). This then causes Soot to set up everything that is required for its classloading.

Let me know if that works.

Best wishes
Eric
