I'm trying to come up with a topic for the next article in my ongoing series on Java 7 over at java.net. So far I've done Building the JDK, superpackages, and java.nio.file. For the next piece I thought about doing JavaDoc enhancements or new features in java.util, but neither of those seems likely to make it in time for Java 7. Ditto closures (not that I really want to take another swing at that particular tar baby) Any suggestions? Anything people particularly want to hear about? If there's something you think might be fun or informative, let me know.
