title: scala.collections.javaconverters._ Error : value map is not a member of java.util.Set
body: <p>I have been using <code>scala.collections.JavaConversions</code> for implicitly converting, but decided to upgrade the scala version and use <code>scala.collections.JavaConverters</code> instead, I'm confused with the explicit conversion with <code>JavaConverters</code>. Can anyone tell me how to convert the below code to use javaconveters.</p>
  
  <pre><code>availableColors.entrySet()
        // Parse the hexadecimal string to the RGB vector
        .map(entry =&gt; (entry.getKey, parseHexColor(entry.getValue.getBackground)))
  </code></pre>
