FULL PRODUCT VERSION :
java version "1.6.0"
Java(TM) SE Runtime Environment (build 1.6.0-b105)
Java HotSpot(TM) Client VM (build 1.6.0-b105, mixed mode, sharing)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]

A DESCRIPTION OF THE PROBLEM :
Web start report an error "Unable to launch the application" with this exception:
com.sun.deploy.net.FailedDownloadException: Unable to load resource ...

This happens only because I install windows xp with the default user name (administrator) in arabic. In this case Java creates a folder in "Documents and Settings" to put the cache and other staff with a name different than the user name which is the non-Unicode representation of the real name in arabic where it should put it under the correct folder.



STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
install windows xp with one arabic user name administrator and try to launch any java web start


REPRODUCIBILITY :
This bug can be reproduced always.
