One more bug in the Currency converter demo, i installed it and run it through WTK21 emulator and when reaching the limit of digits allowed to be entered into the textbox i get the following IAE:
"java.lang.IllegalArgumentException
       at javax.microedition.lcdui.TextField.setChars(+106)
       at javax.microedition.lcdui.TextField.setString(+27)
       at converter.client.Converter.itemStateChanged(+88)
       at javax.microedition.lcdui.Form.callItemStateChanged(+27)

less valuable currencies can overflow when entering big amount of more valuable currency 
(for example Yen will overflow when entering more than 8 trillion US$)
