Unexpected "comments":[] in response

[GoogleCodeExporter]

Facebook now returns field "comments":[] in response for Post's, and that 
breaks:

Exception in thread "main" com.restfb.FacebookJsonMappingException: JSON is an 
array but is being mapped as an object - you should map it as a List instead. 
Offending JSON is '[]'.
    at com.restfb.DefaultJsonMapper.toJavaObject(DefaultJsonMapper.java:135)
    at com.restfb.DefaultJsonMapper.toJavaType(DefaultJsonMapper.java:476)
    at com.restfb.DefaultJsonMapper.toJavaObject(DefaultJsonMapper.java:208)

To fix it, I would add

    if (json.equals("[]")) 
        return null;

in DefaultJsonMapper.toJavaObject(String json, Class<T> type)

And here you should find a lot of examples of this new FB "feature":

Thanks again to the both of you for the bug report and the repro information.

Hopefully will get a 1.5.4 release with a fix out tomorrow.
