[Soot-list] Problem of mapping runnable object to its caller method

[Xinxin Jin]

Hi all,

I have a problem in tracing a runnable object's caller method. To make it
clear, I simplified my code as follows:

public class A {
    public void Foo () {
        Thread t = new Thread(new MyFirstHandler());
    }

    private class MyFirstHandler implements Runnable {
         @Override
         public void run() {
             CreateFile();
        }
    }
}

public class B {
    public void Bar () {
        Thread t = new Thread(new MySecondHandler());
    }
    ....
}

​My problem is : Given method CreateFile(), I want to trace back to get its
caller method. Ideally I should get "A.Foo()".

My algorithm is to use InterproceduralCFG.getCallersOf() provided by heros,
starting from createFile() and tracing backwards level by level:
(1) Get ​<java.lang.Thread: void run()> as the only caller of CreateFile()
​(2) ​Continue to get the callers of ​<java.lang.Thread: void run()>.
 Now you may guess what happens: Because both A.Foo() and B.Bar() call
​<java.lang.Thread:
void run()>, I get A.Foo() and B.Bar() as createFile()'s caller methods.

​So my question is how to remove B.Bar() from my results ?

Thanks a lot !​
