Hi Abdejalil, I post my response to the mailing list since it might help 
other users in the future.

Here Soot tells you that there is more than one method corresponding to 
the name you are looking for ("ambiguous method"). If you take a look at 
java.lang.reflect.AccessibleObject, you will indeed observe the 
setAccessible method is overloaded. In this case, you have to 
disambiguate your query, by using one of the SootClass.getMethod(..) 
variants.

I suggest you use getMethod(String name, List parameterTypes), you just 
have to provide a list of Soot.Type, like:

    List parameterTypes = new ArrayList();
    parameterTypes.add(Soot.BooleanType.v());
    ... = ...getMethod("setAccessible", parameterTypes);

Regards.
