I don't think that a mass rebuild is *required* for this feature.
Packages built with Java 7 should still work with Java 8.

What I said is that it may be nice to do scratch builds of some packages
because they may start failing to build with Java 8.
Some of our CI efforts already caught a few FTBFS caused by switching to
Java 8, for example hadoop[1] or maven-doxia[2].

The earlier we do the scratch builds the more time we'll have to fix any
failures before system-wide mass rebuild comes.
