title: What is "Java error. Invalid format"?
body: <p>I have made my own application in J2me to my mobile phone. The previous versions of this application works perfectly. But now (after a few changes in source code), when I copy this appplication to my mobile phone (Smasung gt-s7550) I get: <code>Java error. Invalid format</code> and the application doesn't start. 
  Do you know what it means?</p>
