for >Java 8 you need to add the JrtInputLocation() to acccess information of the runtime libraries |

Sounds great, but I got another problem. Once I add JrtFileSystemAnalysisInputLocation, I cannot even get the target method via MethodSubSignature correctly. I'll post my new code later. |

Thanks. It seems that this type of InputLocation can solve my problem, but I got another problem since I add this. Please see the follows below. |

When you enable Java modules (what you implicitly did with adding a idFact.getClassType("java.base/java.lang.String") |

Yes, I tried but it still cannot locate the target method. My code: val mainClassType = idFact.getClassType(mainClassName)
val mainClass = view.getClass(mainClassType).takeIf { it.isPresent() }?.get() ?: run {
throw IOException("${mainClassType.toString()} not existed")
}
val allMethodsInMainClass = mainClass.methods.also { methods -> methods.forEach { println(it.toString()) } }
val entryMethodSig = idFact.getMethodSignature(
mainClassType,
idFact.getMethodSubSignature(
"main",
VoidType.getInstance(),
Collections.singletonList(ArrayType(idFact.getClassType("java.base/java.lang.String"), 1))
)
)
val sm: SootMethod = view.getMethod(entryMethodSig).takeIf { it.isPresent() }?.get() ?: run {
throw IOException("${entryMethodSig.toString()} not existed")
}It said: I print the "JavaSootMethod" as |

As titled.
I use SootUp as follows:

I want to know if there are some special handling done for Java 9 or above?
