title: Delimiter doesn't work with UDP
body: <p>My program listen to incoming message using TCP.
  In order to support incoming of multiple messages, separated by new line delimiter, I'm adding the following at the beginning of the pipeline – </p>
  
  <pre><code>New DelimiterBasedFrameDecoder(256, Delimiters.lineDelimiter())
  </code></pre>
  
  <p>The above is working great with TCP. Multiple messages are separated as expected.</p>
  
  <p>The problem is that the code doesn't work with UDP.</p>
  
  <p>Any idea?</p>
