Not sure about a policy, but yes typically we require the previous JDK

the "boot" jdk. However, the policy, if you want to call it that, has
relaxed a bit, it does
need to be a previously released jdk.
We require a jdk6u14 or newer for jdk7, and I suspect the newer jdk6
update releases
also require jdk6u14 or newer as a 'boot' jdk.
The jdk7 javac compiler (langtools repository) needs to build and run
with the 'boot' jdk.
There are other sets of Java sources in jdk7 that may also need to be
jdk6-ish, like the jax*
sources.

I once heard/read that Sun had a policy where JDK N had to built with
the JDK N-1 compiler. I suppose that's not true anymore?
