ImageIcon unable to retrive Image on JVM 1.6!!!

Question

Hello eveybody,
I deployed a desktop JFrame based application using some images.
Actually this app works perfectly on my PC (with JVM 1.5)
Copyiing the jar to another PC with JVM 1.5 I'm unable to retrive ALL images.
code for ImageIcon is this:
icon = new ImageIcon("Excel.png");
1)The same Jar, loaded in a PC works perfect. on the other it's unable to retrieve images (that obviously are packed into the jar...)
2)All the rest of the application works in the right way
do you know why?

Hello.
I have the same issue with all our applets.
When tracking TCP/IP traces, I found a difference between JRE 6u06 and 6u11. In both cases, the java plugins asks 3 times for my jar (why ? Don't know). In 6u6, it waits for each transfer to be completed. In 6u11, the first transfer is ok but the second and the third are termintaed by a TCP connection reset and this is followed by a request to MyApplet.class and another to MyApplet/class.class
Is there a new bug in applet loading ?
Thanks for your help.
