[FIXED] Paging parameters ignored when using Spring @PageableDefault on @RestController

Issue

I'm using Spring-Boot 2.1.6 and I have a Rest Controller that allows for pagination using spring-data's Pageable interface. When I issue a request, defining pagination parameters that are different from the pagination defaults e.g. http://localhost:8080/tasks?size=100&page=0 from an Angular application using Number.MAX_SAFE_INTEGER for the size parameter, I get back 10 tasks (same as the default size in @PageableDefault) even though I've requested 200. And yes, I do have more than 10 tasks

@RestController
@RequestMapping("/tasks")
class TasksController(
    private val taskService: TasksService,
    private val tasksRepository: TasksRepository
) {
    @GetMapping
    fun list(
        @RequestParam(required = false) state: TaskState?,
        @PageableDefault pageable: Pageable
    ): Page<Task> =
        return tasksRepository.findByState(state, pageable)

Solution

It turn out the problem was self-inflicted. Number.MAX_SAFE_INTEGER results in 9,007,199,254,740,991, which is way bigger than Java's Integer.MAX value (2,147,483,648) and the Pageable interface uses int as the type for size.
