Could you please send out a simple test case.
Your code for setting the JSON_ARRAYS property looks fine and the thing should work.
There is even a junit test [JsonXmlStreamReaderWriterTest.testTwoListsWrapper]
for your case.
Could you maybe double-check you added the right names?
I can see add("user") in your first example, and then add("users")
in the second. Are the names correct?
