Many organizations need to have supported 1.7 and 1.8 releases and it's a lot of money to spend on per core licensing which is a new thing after Oracle took over. The link you posted do not have free updated binaries for JDK 7 or 8. For those you have to pay. A lot.
So it makes sense to look for non Oracle JDK and along with OpenJDK, OpenJ9 is a great choice.
