title: Dx warning: Ignoring InnerClasses .. for org.apache.tools.ant
body: <p>I encountered this set of warnings which made memory overflow and eventually crashed Eclipse.</p>
  
  <p>This is an Android application with twitter4J core jar included as a reference library. This is using Google APIs (com.google.android.) so I set the target to Google APIs not general ADK. </p>
  
  <p>Here's the problem.</p>
  
  <p>[2011-11-18 08:29:24 - Twitter] Dx warning: Ignoring InnerClasses attribute for an anonymous inner class
  (org.apache.tools.ant.taskdefs.Parallel$1) that doesn't come with an
  associated EnclosingMethod attribute. This class was probably produced by a
  compiler that did not target the modern .class file format. The recommended
  solution is to recompile the class from source, using an up-to-date compiler
  and without specifying any "-target" type options. The consequence of ignoring
  this warning is that reflective operations on this class will incorrectly
  indicate that it is <em>not</em> an inner class.</p>
  
  <p>This kind of warning continues to an amount of approx 20 inner classes (about 6 in taskdefs), and all inner classes mentioned in the console are from org.apache.tools.ant.</p>
  
  <p>I updated Java SE 6 to 1.6 for Mac OS X Lion with <a href="http://mac.softpedia.com/get/System-Utilities/Java.shtml" rel="nofollow">http://mac.softpedia.com/get/System-Utilities/Java.shtml</a>,</p>
  
  <p>but still the problem exists. Should I upgrade my ant? my ant version is 1.8.2.</p>
