Musings on JDK development

Project Coin at the Java 7 Launch

Update: Video now available from the Project Coin link on this page.

Somewhat before the scheduled GA at the end of the month, today at Oracle headquarters and elsewhere we celebrated the launch of JDK 7.
The webcasts of my half-hour breakout session on Project Coin and three other technical breakouts will be available for replay later. In the meantime, I've posted the slides.

One comment I made during the session made an impression on twitter: after a glitch going back from the NetBeans demo to PowerPoint slides I noted "its always impressive how computers know when you are running a demo." This chronic technological reaction to demos may even last longer than Moore's law!

    I believe you are referring to type variables. It is customary for the names of type variables to single upper case letters; however, type variables can be named like any other identifier if you wish.

    Why is it hard for Oracle to provide download of the Java 7 Launch Webcast video so that developers can play them on portable video players? Microsoft does it all the time. I find it extremely useful.
