The version number for the codebase attribute is incorrect in the following Java SE 6 Java plugin developer guide:

http://java.sun.com/javase/6/docs/technotes/guides/plugin/developer_guide/intranet.html

It describes the version as follows:
"http://my_company.com/plugin/jre-6-rc-windows-i586.exe#Version=6,0,0,99"

Since the fcs build number of Java SE 6 is 105, the correct version should be:

"http://my_company.com/plugin/jre-6-rc-windows-i586.exe#Version=6,0,0,105"

The version number in the mentioned page needs to be changed to 6,0,0,105
Replaced all occurences of Version=6,0,0,99 with Version=6,0,0,105 and pushed the changes to web. It will be reflected in JSC in 48 hours.
