title: What is the "Ignoring InnerClasses attribute" warning output during compilation?
body: <p>I am new to Android and am using the <code>Ical4j</code> library for parsing ICS (Outlook calendar) files.</p>
  
  <p>However, when I build my application in Eclipse, the following warning appears many times in the console:</p>
  
  <blockquote>
    <p>[2010-07-22 15:58:31 - Google Calendar Upload] warning: Ignoring InnerClasses attribute for an anonymous inner class that doesn't come with an associated EnclosingMethod attribute. (This class was probably produced by a broken compiler.)</p>
  </blockquote>
  
  <p>Which implications does this have? How can I resolve this?</p>
