Pattern regex is not being picked by swagger for list of String

[router19]

I have added a below pattern validation for List of String. Though the pattern is picked up by swagger for String type variables while swagger does not pick a pattern for a list of strings.

My class looks like this:

public class Sample {

@Pattern(regexp="[a-zA-Z-]*")
private String key;

private List<@Pattern(regexp="[a-zA-Z]*") String values;

//getters and setters are written

}

The swagger output looks like :

"Sample":{
     "type" : "object"
     "properties" :{
         "key" :{
              "type" : "string",
             "pattern": "[a-zA-Z]*"
         },
         "values": {
                "type":"array",
                "items":{
                     "type":"string"
              }
        }
  }
}

Any help on how can we get Pattern added for List of String
I am using io.swagger version 1.5.19
validation API version -> validation-api-2.0.1

I have submitted a PR #4151 to address this (I was indeed able to reproduce it with a unit test)
