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 of String, String
