Not able to parse if default attribute is an array

[buffe]

The parser failing to parse the default attribute of a parameter if its an array.

e.g:

      {
          "name" : "status",
          "in" : "query",
          "description" : "Csv of user status for which the search is done. Default is Approved and Active.",
          "required" : false,
          "type" : "array",
          "default" : [ "Approved", "Active" ],
          "items" : {
            "type" : "string",
            "enum" : [ "Approved", "Active" , "New"]
          }

after parsing the object will show null value for the default attribute of the query parameter.
