Issues loading java.lang objects into Soot with Scala

[eikNamo]

TL;DR - I'm having troubles making Soot resolve Java classpaths within Scala code. It seems that Soot cannot find java.lang.objects class when trying to load it without an indication where it is looking for it.

The code that is being executed:

import soot.{Modifier, Scene, SootClass}
import java.lang.Object

object SootPlayground extends App {
  Scene.v().loadClassAndSupport("java.lang.Object")
  val sClass = new SootClass("test", Modifier.PUBLIC)
  sClass.setSuperclass(Scene.v().getSootClass("java.lang.Object"))
  Scene.v().addClass(sClass)
}

The stack trace:

java.nio.file.NoSuchFileException: /modules/modules
	at java.base/jdk.internal.jrtfs.JrtFileSystem.checkNode(JrtFileSystem.java:486)
	at java.base/jdk.internal.jrtfs.JrtFileSystem.isDirectory(JrtFileSystem.java:431)

	at soot.SootResolver.resolveClass(SootResolver.java:141)
	at soot.Scene.loadClass(Scene.java:1009)
	...

If I try to omit the Scene.v().loadClassAndSupport("java.lang.Object") line, then the Soot clearly errors about missing classpath for java.lang.object. See bellow:

Exception in thread "main" java.lang.RuntimeException:

Have you loaded rt.jar for Soot framework?

You can add the following lines of code before calling Scene.v().loadClassAndSupport("java.lang.Object")

val libs: String = "<your-path-to-rt-jar>" + File.separator + "rt.jar"
Options.v().set_soot_classpath(libs)
