Java 7

Java7 is on the road ; it is not yet officially available but can be nevertheless dowloaded here.
Here is a sum-up of the embedded libraries in this version :

• Modularity (superpackages and Java Module System)
  

• NIO2 , enhancing the NIO channels
  

• Units and Quantites

• Date and Time API

• Cache API

• Concurrence

• XQuery API

• Resources consumption management

• Swing Application framework

• Beans Binding and Beans Validation

• Java Media Components

• JMX 2.0 and web services connectors for JMX

Along these libraries, the long awaited Block closure feature should also appear. Such a feature could be useful to build DSL like Linq for Java for instance, or groovy-like builders.

For the ones who want already use closures, you can go here.
