[Soot-list] How can I change method's parameters types

[Amir Mehrabi]

Hi Eric
 
This is All of my code
 
class myThread implements Runnable {
  Thread t;
   MyTransformer f;
   String Parameter;
   
   public myThread(String Param){
          Parameter=Param;
          t=new Thread(this);
          t.start();
   }
 
   public void run(){
      f= new   MyTransformer();
      PackManager.v().getPack("jtp").add(new Transform("jtp.trnsform",f));
      String[] Args=Parameter.split(" ");
      soot.Main.main(Args);
   }
 }
 
class MyTransformer extends BodyTransform{
 
internal Transform(Body b ,String Phasename,Map Option){
 
   List args=b.getMethod().getParameterTypes();
   b.getMethod.setParametersType(args)
 
}
 
}
 
 
 
And in my program just initiate myThread like this:
  ...
     private void jButton1ActionPerformed(java.awt.event.ActionEvent evt){
             myThread t=new myThread("-app Test.TestClass3");
    }
...
 
Thanks

Well, apparently whatever list throws this exception is being modified
while somebody (presumably your manually created thread) iterates over
it. Are you instantiating multiple such threads or just one? It's hard
to say. I guess you need to use a debugger there...
