Wow, the exact phrasing is:

> Building JDK 8 requires use of a version of JDK 7 that is at Update 7 or newer. JDK 8 developers should not use JDK 8 as the boot JDK, to ensure that JDK 8 dependencies are not introduced into the parts of the system that are built with JDK 7.


So: If you intend to develop on JDK 8, don't use JDK 8 as boot JDK.

That is, to avoid that building JDK 8 requires JDK 8.

We're packagers, we're not the target for neither the warning nor use-case ;)

Best regards
