title: Java: Passing multiple values to handlebar template
body: <p>I am using handlebar templates to prepare email content dynamically before sending over it.</p>
  
  <p>It's straightforward to pass just one value. For example:</p>
  
  <p><code>What's up {{this}}</code> template workes fine with <code>template.apply(firstName)</code>.</p>
  
  <p>Tried changing the template to <code>What's up {{this}}, {{this}}</code> and try to fill in by <code>template.apply(lastName);</code> and <code>template.apply(firstName);</code>.</p>
  
  <p>But it doesn't work.</p>
