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

[Amir Mehrabi]

Hi Eric

For your idea I write a class like this:
 
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);
   }
 }
 
And in my program just initiate myThread like this:
  ...
     private void jButton1ActionPerformed(java.awt.event.ActionEvent evt){
             myThread t=new myThread("-app Test.TestClass3");
    }
...
 
 
But unfortunately I receive an exception again :
 
    Exception in thread "thread-2" java.util.ConcurrentModificationException
    at 
java.util.AbstractList$Itr.checkForComodification(AbstractList.java:372)
    at java.util.AbstractList$Itr.next(AbstractList.java:343)
    ....
 
I don't know what's the problem!
Please help me.
 
Thank you
 
Amir Mehrabi J.

Hi Amir.

To me that seems like a threading problem, not a problem with Soot.
Are you running your Soot within the AWT event-dispatch thread? If so,
you may need to change that.
