in swagger JSON, if paramType = body, and there is "items" - parameter type is absent, so get items.type instead.

Hi
Could you please check it out and merge/fix is appropriate. thanks!

here is sample piece of JSON:
...
{
              "name":"body",
              "description":"Tag map [name, value]",
              "required":true,
              "allowMultiple":false,
              "items":{
                "type":"string"
              },
              "paramType":"body"
            }
...
the parameter actual type (in Java code) is Map<String, String>
