Oracle still supporting Java 8, but Java 9 is not available for support.
what could be the reason?

Answer 1

You should read this, Oracle changed the support policy:
http://www.oracle.com/technetwork/java/javase/eol-135779.html

There are versions with LTS (long term support) like java 8 and in future with java 11. And non-LTS like java 9.

And thanks for asking it.
