Fix the version of required jdk

[KUBOTA Yuji]

Hi everyone.

configure of jdk9 (and build-infra/jdk9) requires boot jdk version is 8 or 9.
But help message requires jdk7. Especially, yum_help requires JRE.
So I create a small patch to fix, please someone review it?

I do not have an account of openjdk, so I want a sponsor.
