'@QueryParam of a List throwing NumberFormatException

I have an endpoint defined as:

    @GET
    @Produces("application/vnd.campus.api.v1+json")
    public Response getFiles(@QueryParam("category-type") List<Long> categoryType,
                             @QueryParam("extension-type") List<Long> extensionType,
                             @DefaultValue("") @QueryParam("query") String query,
                             @DefaultValue("date") @QueryParam("order-property") String orderProperty,
                             @DefaultValue("desc") @QueryParam("order-direction") String orderDirection,
                             @DefaultValue("1") @QueryParam("page") Integer page,
                             @DefaultValue("10") @QueryParam("page-size") Integer pageSize) {
        ....
    }

but when i make an call to: http://localhost:8080/files?page=1&pageSize=10&category-type=1,2&order-property=date&order-direction=desc&extension-type=2

I get a NumberFormatException (i don't even enter the controller, i just catched the exception with an exceptionmapper): enter image description here
