NPE in parse of update response

[juniorklein]

Hi,
When when perform a call to get the user network updates I got an NPE exception.

The stacktrace is:

java.lang.NullPointerException

Debugging the code, I found the problem. The response sent by LinkedIn is invalid because doesn't have updateContent.
This is JSON response for update with problem:

{
    "isCommentable": true,
    "isLikable": true,
    "isLiked": false,
    "likes": {
        "_total": 10,
        "values": [
            ...
        ]
    },
    "numLikes": 10,
    "timestamp": 1401725796929,
    "updateComments": {
        "_total": 0
    },
    "updateContent": {},
    "updateKey": "UPDATE-19924-5879264111107284992",
    "updateType": "SHAR"
}

In line 88 from LinkedInNetworkUpdateListDeserializer class, when jackson attempts to readValue from a null person, the NPE is raised.

This is an error in linkedin spring social or in linkedin?

Thanks
