Got warning downloading Java SE from Google Chrome, went from https:// to http:// page. Just wanted to confirm that this is an Oracle download site.
No idea what went wrong. Use this link: Oracle Software Downloads | Oracle Technology Network
are you using some sort of download manager? Akamai is used by several companies like Adobe for that, but AFAIK not by Oracle.
Scan your machine for the re-direct virus that has been going around and remove it.
