A DESCRIPTION OF THE PROBLEM :
Using the sample draggable applet example at https://jdk6.dev.java.net/plugin2/ the desktop icon is created.

When executing the desktop icon this output is received:

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Set Firefox 3 to use libnpjp2.so from java 6u10 b32.  Drag the applet at https://jdk6.dev.java.net/plugin2/ out of the window and allow the desktop icon to be created.

Close the browser and the applet.

Double-click on the icon and note that the applet does not restart.

View the icon properties and execute the command at a command prompt to receive the MalformedURLException.


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I was expecting the applet to restart.
ACTUAL -
The applet failed to restart.
