Isn't what i do when i declare the Class [] params =
{com.arso.trelaze.socle.persistance.Reader.class}; before calling addCallMethod ?
And when i check my log i see that the factory create the RWClass which implemente
Reader so they can't be a class cast problem.
Maybe i should create a beaninfo in my sub class to be sure introspection
match the corect class
Is some had this kind of problem ?

i suggest that you check that the parameter type matches exactly the
method call signature: the CallMethodRule is very particular about the
type parameter.
