Just back from Brazil and no time to catch my breath … so much happening:
- JavaOne Latin America was a blast – so much enthusiasm in the developer community! Check out some of the videos and podcasts, including the JavaOne Community Keynote, OTN interviews with a variety of Java luminaries, as well as the Java Spotlight Podcast #60: JavaOne Latin America: Videos and Podcasts
- Java 7u2 has been released, featuring an updated VM, support for Oracle Solaris 11, support for Firefox 5 and later, and security fixes. Also, JavaFX 2.0.2 is now included with Java SE to make developing and running JavaFX applications even easier: Java SE 7u2 Release Notes, JavaFX 2.0.2 Release Notes
- Aligning with mainline JDK development, Java SE Embedded 7u2 has been released as well. This release includes new ports to Linux on PPC and performance improvements on ARM systems by 20-40%. Also, Oracle intends to port JavaFX to Linux on ARM in order to support a broad range of platforms from mid-range embedded all the way to desktops: Henrik’s blog on the Java SE Embedded 7u2 release.
- Lots of activity around JavaFX as well – interest is really taking off. Point in case: A new project, eFX, has been started on java.net aiming to create a generic application framework for JavaFX 2.0 based on the NetBeans platform: Geertjan’s blog on eFX
- Finally, OTN put together a list of their “Most Popular Tech Articles of 2011”. Java topics, from Java SE 7 and 8 features, Java EE 6, JSF, and JavaFX dominate the list. Have a look: Our Most Popular Tech Articles of 2011

Finally, I get a chance to catch my breath. JavaOne has been extremely busy and while there are still a few hours of good talks to go here is a quick summary so far:
General observations:
The vibe is very positive. Attendance is significantly up over previous years and the show is well organized. Feedback from attendees has been very excouraging – lots of good buzz on #javaone and other social channels. Many sessions are sold out or standing-room only.
Announcements:
This year’s JavaOne left no doubt Java is moving again, and picking up steam. Throughout the conference and in the various keynotes there was a host of announcements, strategic initiatives, roadmaps, product releases and updates.
I’ll try to summarize, focusing on the Java Platform, Java SE, and Java ME technologies:

-
- Submission of new JSRs over the coming months
- Updates of the CLDC Platform VM and library specifications to enable better alignment with Java SE 7 features
- Creation of a “CDC Profile” in Java SE 8, which allows deployment of Java SE 8 implementations in resource-constrained environments
