title: Regex to remove Java comments block containing specific words
body: <p>I am trying to remove comments containing a specific Java doc comment</p>
  
  <p>Eg. I want to remove this comment block</p>
  
  <pre><code>/**
   * @author: Bob
   * @since 28.mar.2008
   *
   */
  </code></pre>
  
  <p>But not this block</p>
  
  <pre><code>/** 
   * This class represents ...
   *
   * and so on 
   */
  </code></pre>
  
  <p>So far I have this regexp:</p>
  
  <pre><code>^/\*\*(.|\s)+?\*/
  </code></pre>
  
  <p>Which matches a block comment</p>
  
  <p>But I need to some conditionals somewhere in there (eg. block comment that contains "@since"
  I guess the key is to use look aheads, but my regex fu is not that good at the moment.</p>
  
  <p>Any one who can help me improve this</p>
  
  <p>Thanks in advance 
  Bob</p>
