how do I pass the selected parameters in the checkbox from one jsp page to another jsp page?

I have to make the switch to selected values ​​within some checkboxes in a jsp page but after the selection and after pressing the "Send" button, I generate this error with the following description: HTTP Status 400: The request sent by the client was syntactically incorrect.

Where am I wrong?

TaskController.java

@RequestMapping(value="/newTask", method = RequestMethod.GET)

        String s = auth.getName();
        Student student = studentFacade.retrieveUser(s);
        List<Job> jobs = new ArrayList<>();
        if(!(auth instanceof AnonymousAuthenticationToken)) {
            jobs = facadeJob.retriveAlljobs();
            model.addAttribute("job", getMathRandomList(jobs));
            model.addAttribute("image", imageFacade.retriveAllImages());
            List<Image> img = imageFacade.retriveAllImages();
            task.setImages(img);
