Greetings.
The JDK 7 build has been using -source 7 for some time, but to date use of
new language features has been informal and incidental. Supporting Project
Coin and JSR 334, Stuart Marks will be leading a "minting" exercise over the
JDK code base to systematically update the JDK libraries to take advantage
of the Project Coin language features. Efforts will be focused on the src
and test portions of the jdk repository of the JDK 7 forest. [1] The first
features to be rolled into the code will be diamond and strings in switch.
It would be really great if the compiler code remains able to be built
using a Java 6 bootstrap.
(So that everyone's build environment doesn't become reliant on
pre-FCS quality code).
Yes, we plan to keep at least the javac portions of the langtools
repository buildable with JDK 6 for just such bootstrapping reasons.
For some time, we've had the constraint that javac in JDK (N+1) is
buildable with JDK N, which precludes use of new language features and
direct use of new libraries (reflection can be used for dynamic lookups
of course).
