Java SE 6 Update 10 has shipped!!

Download Java SE 6 Update 10 release now!

This update release introduces new features and enhancements aimed at providing an optimized consumer end user experience. Java SE 6 Update 10 focuses on the following areas:

  • Enhanced JRE installation experience
    • The Deployment Toolkit takes the guess work out of determining what versions of the JRE end users have installed on their PC. It supplies Java based web applet/application deployers with a simple interface to accomplish Java detection and installation.
    • The Kernel online installer (JRE only) lets first time Java users run applets and Web Start applications without waiting for the whole JRE download. The default Kernel installation is expected to satisfy the requirements of most Java applets and applications, and any additional libraries that may be required at runtime are downloaded to complete the Kernel installation. This installation mechanism let the end user get up and running significantly faster, while the complete JRE installation takes place in the background. See Java Kernel FAQ for more information.
    • For current users of Java SE, the JRE update mechanism has also been improved, using a patch-in-place mechanism that translates in a faster and more reliable update process (the patch in place mechanism will take effect for end users who upgrade from this update release or later to a new update release). As an added benefit, follow-on update releases will no longer be listed as separate items in the Windows "Add or Remove Programs" dialog.
  • Improved performance and look & feel
    • The Java Quick Starter feature will prefetch portions of the JRE into memory, substantially decreasing the average JRE cold start-up time (the time that it takes to launch a Java application for the first time after a fresh reboot of a PC).
    • Hardware acceleration support: Java SE 6 Update 10 introduces a fully hardware accelerated graphics pipeline based on the Microsoft Direct3D 9 API, translating into improved rendering of Swing applications which rely on translucency, gradients, arbitrary transformations, and other more advanced 2D operations.
    • A new cross-platform Swing look & feel, Nimbus, provides a nice update over 'Metal' and 'Ocean'.
  • Next-Generation Java Plug-In
    • A new implementation of the Java Plug-In that is designed to address long-standing issues with applets, and which features improved reliability, the ability to specify large heap sizes, the ability to select a specific JRE version to execute a particular applet, improved Java/JavaScript interoperability, and better support for signed applets on Windows Vista.
  • Unify Browser and Desktop Experience
    • The new draggable feature in Applet unifies user's browser and desktop experience - The New Plug-In allows you to drag an Applet off from a browser to your desktop and allows your Applet continues to run. In addition to dragging an Applet off from a browser, when user closes the a shortcut can also be created from this draggable Applet. The shortcut utilizes Java Web Start technology and allow user to launch the Applet with Java Web Start without opening a web browser. Thus, this feature unifies desktop application deployment via Java Web Start technology, and Applet deployment inside the browser.
  • New Version Download and Pack200 Support
    • We introduce new Java system properties to support the usage of version download and Pack200 without any server side requirements. This addresses the issue that is raised in RFE 6378311.
I'd say, download Java SE 6 Update 10 if you haven't already, take advantage of the above consumer features, create draggable applets to allow your users to drag it off from the website, point your users to the Kernel installer so they can have a faster installation experience, and use Java Deployment Toolkit to easily detect and deploy a suitable JRE for your applications.

Happy coding~! :-) 


Great work !

But does it contain 64bit version of Java WebStart/JNLP and browser plugin ?

The problem is that nobody can stop customers from installing 64bit Java if they bought brand new 64bit computer with 64bit OS.

Awesome! I've been waiting for this. I'm working on a pure Java MMORPG, but my users have not had a good experience with Java Web Start. I'm really glad Sun/Java decided to seriously pursue improvement of the end-user experience. As soon as I can test it, I'm going to officially recommend my playtesters upgrade.

From what I understand, it does not yet have support for applets in the 64bit VM. I think the current roadmap has that planned for 6u12.
