Hi,
I'm hitting the issue 300 on 1.1.5-ea-SNAPSHOT:
I'm sending an empty array in a JSON string, and it does not
unmarshall to empty array or even to a null object, which I could work
around. It just throws a NPE.
"{"id":27,"name":"ABC","description":"","links":[],"children":[]}"
java.lang.NullPointerException
