That's at runtime, right? I'm thinking more about the possibility of
it breaking the build
on some architectures.

We're still in a state of flux with jdk8u right now, until a new lead
is assigned, but I'm
thinking it makes sense to keep both the jdk8u and jdk8u-dev
repositories, and do
releases from the former after they've baked in the latter. With
something like this,
it may even be worth getting a further tree where it can be tested and
worked on,
without the pressure of the three month update cycle.
