Hi guys
I'm trying to use Soot with vasco(https://github.com/rohanpadhye/vasco) to perform SignAnalysis.
But I get IllegalArgumentException about SootMethodRefImpl.

In SootMethodRefImpl, it looks returnType null check(Line:85) and error occurred from that line.
So I tried to figure out class and method name, finally I got error caused by "sun.reflect.annotation.AnnotationType" class and "retention" methods.

It seems like those are related to annotations but my main_class does not have "retention" annotations.
How can I solve this problem? Plz give advice!
Thanks

Those are caused by junit.framework.testsuite
But I still cannot understand why error related with retention annotations

The easiest way to suppress the thrown exceptions is setting Soot options:

• in programming way:Options.v().set_allow_phantom_refs(true);

• or in command line options way: -allow-phantom-refs

But I think it's not a correct way to solve the problem.

Days ago, the problem bothered me a lot. And now I think I have solved the problem.
Pull Request have pushed, look at #1697

@canliture
Thanks for reply. I tried with your changes, but I still get same errors.
Maybe my error from other issues.

please give me the files that can reproduce the crash，I think I can solve the problem.After all，I have solved the problem in my environment.

By the way，what version you are using？4.3.0-snapshort？what thunk version？

@canliture
I was using 4.2.1. After some effort, I finally caught my error was related to Java heap memory.
Thanks for your attention.
