Subject Re: Change rest-http Java to JSON null transformation logic
Date Thu, 16 Jun 2016 10:12:03 GMT
Den, that was my main reason "consistency". Strings in java can be "null"
and can be empty. But after serialization we lost this info.
As for compatibility - I'm afraid it is impossible to fix. Only to change
user code.
