title: Bad base-64 error
body: <p>I'm getting a "java.lang.IllegalArgumentException: bad base-64" on the following code:</p>
  
  <pre><code>byte[] msgBytes = Base64.decode(msgStr, Base64.NO_WRAP);
  </code></pre>
  
  <p>msgString is a String, and right before this line, I check the value of msgStr and it is "fl-ILw==". Is there anything wrong?</p>
  
  <p>Thanks.</p>
