I remember the exact date when Mustang got released. Mustang is going great because of it's deadly features like JS support, Annotations and many more.
Moving forward to JDK 1.7-Dolphin which has a expected release in 2008! Whats new ?
I am making a complete presentation on Dolphin and will upload it soon ! Proposals are:
1. SuperJAR's - this is something really cool
2. Co-bundling with other language interpreter like JRuby, Jython.
3. Closures in java - something in one line we can understand local variables for a function - kept alive after the function has returned
4. More enhancement with Java Persistence API
and many more ...
The new JDK comes into a new flavor of open source, so get ready >
