I tried it on a complicated source file and it works.

Jens Gerlach suggested in private mail to use option -then. I tried
-then -jessie -jessie-atp=gui after calling my plugin, but it didn't
work as I expected. My plugin is supposed to erase all function
contracts by

method vfunc _ = begin
    let new_kf = Cil.get_kernel_function (Cil.copy_visit ()) (Extlib.the
self#current_kf) in
    Kernel_function.set_spec new_kf (fun fs -> Logic_utils.clear_funspec
fs; fs);

but they are still present in Jessie. If I set the current project to
File.create_project_from_visitor, then the input for Jessie is empty.

Best regards,
