Joe Darcy posted Project Coin: The Final Five (Or So) late last week. Joe also posted the content of this blog on the coin-dev mailing list, which Remi Forax references in his insightful post The seven small languages changes that will be in JDK7.
Here are the changes accepted for inclusion in JDK 7:
- Strings in switch
- Automatic Resource Management
- Improved Type Inference for Generic Instance Creation(diamond)
- Simplified Varargs Method Invocation
- An omnibus proposal for better integral literals
- Language support for Collections
- Language support for JSR 292
Joe notes that:
The specification, implementation, and testing of these changes are not final and will continue to evolve as interactions are explored and issues cleared.
Remi found the final list a bit surprising:
About Language support for collections, hum, I was a complete surprise for me, knowing that Joe said more than one time than only 5 proposal will live in jdk7.
He also notes the looming deadline:
The deadline is short, end of October, I think help of the community is needed so if you want to see a better support for collection in Java, join us on coin-dev list and help to define/implement this feature.
Joe takes the time to talk about three proposals that went through further consideration, but were not ultimately accepted for inclusion in JDK 7:
About improved exception handling, Joe notes:
Improved exception handling would be a fine change for the language, but it ventures near the type system and we do not estimate we have resources to fully develop the feature within JDK 7. I would like to see improved exception handling reconsidered in subsequent efforts to evolve the language.
In Java Today, Joseph Darcy has posted Project Coin: The Final Five (Or So) : "First, thanks to all those who submitted interesting proposals and thoughtful comments to Project Coin; a demonstrably vibrant community wants to evolve the Java programming language! Without further ado, the final Project Coin changes accepted for inclusion in JDK 7 are..."
Robert Eckstein has published a new article on the Sun Developer Network, Mixins in JavaFX 1.2 Technology: "With the release of version 1.2 ofJavaFX technology, developers have a new style of class inheritance: a mixin. A mixin is a type of class that can be inherited by a subclass, but it is not meant for instantiation. In this manner, mixins are similar to interfaces in the Java programming language. However, the difference is that mixins may actually define method bodies and class variables in addition to constants and method signatures..."

TOTD #97 showed how to install GlassFish Tools Bundle for Eclipse 1.1. Basically there are two options - either install Eclipse 3.4.2 with WTP and pre-bundled/configured with GlassFish v2/v3, MySQL JDBC driver and other features. Or if you are using Eclipse 3.5, then you can install the plug-in separately and get most of the functionality. TOTD #98 showed how to create a simple Metro/JAX-WS...

In the current Spotlight, the java.net Java Communications Community announces that SIP Communicator now supports file transfers: "The SIP Communicator project is proud to announce that it now supports file transfer for most protocols supported by SIP Communicator. Starting from build 2002 SIP Communicator users would be able to share files via the XMPP, MSN, Yahoo! Messenger, ICQ and AIM protocols. You can download the application at http://download.sip-communicator.org This implementation is part of an effort funded by the NLnet foundation. However, early research on the subject started long ago and many have contributed."
The current java.net Poll poll asks "Which aspect of java.net occupies the most of your time?"Voting will be open through early Friday.
