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:

- Oracle announces plans to evolve the Java ME Platform and align Java ME with Java SE 7 through:
-
- 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
