Java7 launch event in Tokyo

In yesterday, Java7 launch event was held at Aoyama, Tokyo. the program is like below:

1. Opening
2. Summary of Java7 & Java8
3. HotRockit / New licenses for Java
4. NetBeans 7.0 / Project Coin
5. InvokeDynamic
6. Fork/Join Framework -> Lambda
7. More new I/O
8. Lightning talks

I had two thoughts from this event.

• Both G1GC and InvokeDynamic are great technologies. It's good news for LLs (like JRuby) on JVM.
• But, new Java7 features for Java language are imperfect because there are lack of lambda. Those features will become perfect since Java8.

And most funniest talk is about "JRuby and invokedynamic".
