Comments
It was found out that this bug was resolved in JDK 7 by the fix for the bug JDK-6957030 in 2011. But that fix was not ported to JDK 6. It was proven in local environment, that the fix for the bug JDK-6957030 resolves the bug in JDK 6, therefore a solution for this bug should be porting of the fix for the bug JDK-6957030 from JDK 7 to JDK 6.

The bug is reproducible with any release of JDK 6 only on the next Linux OSs with GNOME desktop: Red Hat Enterprise Linux (RHEL) 6.2 or Oracle Enterprise Linux (OEL) 6.2. The bug is not reproducible on older releases of these OSs, like RHEL 5.6, or on other distributions of Linux OS, like Ubuntu or openSUSE. The bug is not reproducible with JDK 8 or JDK 7. Analysis showed that a reason of this bug is absence of execute "x" permission for the owner "u" of the shortcut file created by Java Web Start. Thus the command provided below allows to display a proper icon and name of the shortcut on a desktop. chmod a+x <SHORTCUT_ABSOLUTE_FILE_PATH>
