Hi all
I want to change type of my method's parameter
How can I do this?
for example 
I Have a method like :
            public void sample(int a,TestClass c);
 
I want to change the type of these method to
            public void sample(int a,long c);
 
when I want to do this in BodyTransformer , soot throws an exception , the 
following code are a portial of my code

...
protected void internalTransform(Body body,String phasename,Map option){

List lst=body.getMethod().getParameterTypes();
for(int i=0;i< lst.size() ; i++)
{
     lst.add(RefType.v("MyPackage.MyClass"));
}
body.getMethod.setParameterTypes(lst);          <==== throws an exception
...
}


     THROWS :
