Darija Radchenko opened SPR-15978 and commented

I'm really sorry, I fill confused about this, but as listed here we are enable to handle custom http status codes already... But I'm still getting
IllegalArgumentException: no matching constant for [230] caused in MessageBodyClientHttpResponseWrapper.hasEmptyMessageBody().
I'm using API that responses 230, 240 codes etc... Can you please provide some example or guide me somewhere I can find the solution?
