Doubt about message

Hi!
I am working on MIDP using the J2ME Wireless Toolkit which I have downloaded from java.sun.com.It is the older version and not the new one.And I have jdk1.3.
When I am running my own code in the toolkit, there is a message I am getting.The code seems to run fine though.The message is :
Could not create icon com.sun.midp.midlet.Selector$MIDletInfo@8e
But when I am running the example given with the toolkit...there is no message and the code runs fine.
What could be the problem?
