Many open source projects are aggressive, such as Oracle JDK and Ubuntu, But they provide
stable commercial supporting.

supporting old versions of jdk is one of the key revenue streams for oracle's sun group: there's
a lot of webapps out there which need a secure/stable JDK version, and whose owners don't
want to spend time & money doing the upgrade.

In other words, the enterprises doesn't drop JDK7, might aslo do not drop Spark 1.x to adopt
Spark 2.x early version.

probably true, except for the complication that in a large multitenant cluster, you need to
get everyone who runs code in the cluster and the ops team happy with the plan
