title: Spring boot validation annotation not working for Kotlin
body: <p>I got a simple data class for Kotlin</p>
  
  <pre><code>data class Person(val name: String, @get: Min(18) val age: Int)
  </code></pre>
  
  <p>I actually build this class from a CSV file and I read the CSV using apache CSV parser. Even I have some data which is less than 18 for <code>age</code> field, the test still passed no error.</p>
  
  <p>Looks like this annotation is not working for Kotlin?</p>
