The JDK7 developer preview is now available.
The following are what I’m looking forward to the most amongst all the new features.
- Concurrency and collections updates (jsr166y)
- JSR 203: More new I/O APIs for the Java platform (NIO.2)
- Enhanced JMX Agent and MBeans
We’re already using jsr166y and extra166y with Java 6 at work amazingly.
