JSR 203 promises more new I/O APIs for Java, including several new I/O abstractions and a new I/O programming model. In the interview More New I/O APIs for Java, JSR 203 spec lead Alan Bateman explains how JSR 203's file API solves current shortcomings with java.io.File, the new Watchable interface, and asynchronous I/O programming. Bateman is an engineer in the SE Core Technologies team at Sun.

Neal Gafter: A Limitation of Super Type Tokens
I slightly modified the clock example Chris Oliver wrote, and added some artwork to it so it looks somewhat like one of the Google desktop gadgets I use. The gadget is very low res, so I decided to make the image files much bigger so users can resize it without it looking like a pixelated mess. I made the seconds hand jump every second instead of moving continuously, and like the gadget, it has a very quick animation that moves the hand back a bit to give it a "spring" feel...

Neal Gafter: A Limitation of Super Type Tokens
There was a coincidental adjacency between two slides in Josh Bloch's talk that made me think a bit more about the idea of Super Type Tokens. The last slide of his discussion of generics gave a complete implementation of the mind-expanding Typesafe Heterogenous Containers (THC) pattern using Super Type Tokens...

Adding Typed Support to the StAX API:
A discussion has been started in the stax_builders@yahoogroups.com mailing list about typed extensions to the StAX API. We hope this discussion will serve as the basis for a proposal to be incorporated in the next release of the API. Subscribe to the mailing list (it is moderated) if you are interested in influecing this next-gen API.
