Thanks to Joe, Jon, and Wei.

Also, the JDK will be build using -target 5 from now on. Previously, we shipped with -target 6 to allow thorough testing of the new verifier. However, we always planned to ship with -target 5 in Mustang RC. The reason for this is very simple: we want people to upgrade to Mustang as soon as possible. One problem we identified in JDK 5.0 was that customers running any kind of app server will run into a problem if the app server has a built-in compiler that doesn't understand the new class file format. Fortunately, there is a very simple solution to this for Mustang: use the old class file format.
