I have not found anywhere to suggest JDK 7 should not work with Java EE7.
If you feel the links cannot be trusted, please reach out to the spec lead
of Java EE7 for confirmation.
Many thanks,
Emily

I wouldn't put much trust into a blogpost.
Anyhow the article basically encourages you to use JDK 8 features with
EE7.

Java EE 7 SDK != Java EE impl. Besides it says you can use 7 or 8 and
recommends latest JDK release anyway.
I was expecting these limitations to be present in EE umbrella spec or
something like that (imposing minimal version on implementations) but
found none so far.
