Cached Flux with multiple values returns list wrapped in Flux

[tPeltola]

Expected Behavior

Cached Flux (or any Publisher) with multiple values should return a Flux containing the same values. (Or fail instantly, if this should not be supported.)

Actual Behaviour

Cached Flux returns a Flux with the values wrapped in a List.

Steps To Reproduce

1. Return Flux with multiple values from a cached method

    @Cacheable(cacheNames = ["sample"])
    open fun flux(first: Int): Flux<Int> = Flux.just(first, first + 1)

2. Call the cached service collecting the result
3. Observe the result is list of list with values
