The sponsor text on the SetupCompleteSuccess final dialog is a different font and larger than needed i.e. TahomaBold10 instead of only needing to be MSSansBold8.
See the Java Setup - Complete dialog at http://xdesign.sfbay/projects/java/j2se/consumer/Install/6u5_installer.html.
The attachment shows German which is addressed in 6732071.

English, Spanish, French, and Italian should be changed.
I don't know about Japanese, Korean, Swedish, Simplified Chinese, and Traditional Chinese.
In sponsors\make\installer\bundles\windows\ishield\transform\jre\partialtables\ISString.idt:
IDS_OO6 1033 {&TahomaBold10}You have Successfully Installed Java along with the OpenOffice.org Installer. 0 -1021928859
IDS_OO6 1034 {&TahomaBold10}Ha instalado Java correctamente, as como el instalador de OpenOffice.org. 0 -711236145
IDS_OO6 1036 {&TahomaBold10}Java est maintenant install avec l'installeur de OpenOffice.org. 0 -711240913
IDS_OO6 1040 {&TahomaBold10}L'installazione di Java e del Programma di installazione di OpenOffice.org sono state eseguite correttamente. 0 -711209649
The "You have Successfully Installed" . . . text on the SetupCompleteSuccess final dialog should be MSSansBold8 for all languages other than Japanese.

When no sponsor is installed, "You have Successfully Installed Java™" is already MSSansBold8 for the 9 languages.
