receive sqs message attributes using the camel dsl?

anybody knows how to receive sqs message attributes using the camel dsl in java? Im getting the following error:

"Failed to create route payee route: Route(batch route)[[From[aws-sqs://myqueue?amazonSQSEndpoint=... because of Failed to resolve endpoint: http://aws-sqsmyqueue?amazonSQSEndpoint=sqs.us-west-1.amazonaws.com&accessKey=*****&secretKey=****************&maxMessagesPerPoll=1&messageAttributeNames=%5BuserID%5 due to: Could not find a suitable setter for property: messageAttributeNames as there isn't a setter method with same type: java.lang.String nor type conversion possible: No type converter available to convert from type: java.lang.String to the required type: java.util.Collection with value [userID] "

please find my code

StringBuilder QueueURI = new StringBuilder();
    QueueURI(PropertyUtils.AWS_SQS)
            .append(propertyUtils.queueName)
            .append(PropertyUtils.AMAZON_SQS_REGION)
            .append(propertyUtils.sqsRegion);
    QueueURI(PropertyUtils.AWS_ACCESS_KEY).append(
            propertyUtils.awsAccessKey);
    QueueURI(PropertyUtils.AWS_SECRET_KEY).append(
            propertyUtils.awsSecretKey);
    QueueURI(PropertyUtils.MAX_MESSAGES_PER_POLL_1);


Collection<String> collection = new ArrayList<String>();
    collection.add("userID");

//aws-sqs://myqueue?amazonSQSEndpoint=sqs.us-west-1.amazonaws.com&accessKey=*****&secretKey=****************&maxMessagesPerPoll=1&messageAttributeNames=[userID]



from(QueueURI.ToString() + collection)
            .routeId("batch route")
            .process(userValidator);
