"After an initial round of testing we've declared build 147 to be
the first Release Candidate of JDK 7. There are only thirteen changes in this build. Over half of
them are administrivial updates that don't affect the actual code; the
remainder are true showstoppers, including several hard VM crashes and
a JIT correctness bug identified by an Eclipse unit test. If no new showstopper issues are reported, and if JSR 336 and the
component JSRs pass their Final Approval Ballots in the JCP, then this
will be the GA build for release later this month per the schedule
posted back in January."

Yeah, Java has excellent numeric performance, there's no way flash could compare; to be fair, ActionScript is not really designed for performance the same way Java is.
On the other hand, startup time and Swing performance have been constantly disappointing for normal desktop users: even on my relatively new laptop, IDEA's menus somehow feel slow and unresponsive to pop up compared to any native program.
With the JVM being such an attractive target for alternative language implementations (hopefully getting tailcalls _someday_), one can only hope Oracle can fix-up these final minor flaws with the new JVM, and who knows what the merger of also-Oracle-owned JRockit's techniques can further do for performance.

I think if you could compare two current applications running inside the webbrowser, one made with the latest Flash release and the other one using JavaFX running on top of the latest JVMs, the performance would be comparable or, probably (I'm just speculating here) would be better in the Java side.
Well, given how bad Flash performance is on most mobile/tablet devices (and even some desktops), comparing Java and Flash performance is like comparing the shit I took last night with the shit I took this morning. Either way, it's still shit.
At work, we have Java apps running on servers inside of tomcat/resin instances, and we're constantly having to restart them because of OutOfMemory errors and cpu spikes. For some of them, we have to restart them once or twice a day via crontab, because the architects can't figure out WTF is causing them to wig out and swallow up RAM/CPU resources like a Hoover. Of course, I did not write these apps, so who knows how well written they are, but it seems like Java is a hog no matter what environment it runs in.

I use Jboss for all my java and java/flex applications at work. We do not have these problems when the applications are coded properly, and on proper hardware.
So ... it's either a coder issue, a tomcat issue or hardware issue. Nothing to do with Java.
Replace those developers, they are a waste of time. Or .. it could be one of those management "decisions". In that case, replace those managers ...

So, the Xbox One disaster continues. Microsoft's policy for dealing with the used games market has reportedly leaked - and it's a clear and direct attack to destroy the used games market. Prices for used games will be set at the retail value of a new game, and retailers have to hook into Microsoft's computer systems and comply with Microsoft's terms and conditions.

At an event earlier today, Microsoft unveiled the next Xbox - the third model, but confusingly named Xbox One. The big focus was TV, integrated Kinect, and all the other stuff we all expected to be forced down our throats. I think it took them 25 minutes to actually come to what should be the core of the story: gaming. Nothing groundbreaking in the gaming department, except for how Microsoft intends to handle the used games market and borrowing games from friends: pay up, buddy!

The day has finally come! Jolla has finally announced the launch device for its Sailfish operating system - and by god this is a looker. It's decidedly different from other phones out there, but it has good specifications and carries a relatively reasonably price tag - EUR 399, and it's up for pre-order today, shipping in the fourth quarter of this year.

Why does Google get so much credit in the technology industry? Why, despite the company's many obvious failings, do many geeks and enthusiasts still hold a somewhat positive view on the all-knowing technology giant? A specific talk at Google I/O this week provides the answer.

"Windows is indeed slower than other operating systems in many scenarios, and the gap is worsening." That's one way to start an insider explanation of why Windows' performance isn't up to snuff. Written by someone who actually contributes code to the Windows NT kernel, the comment on Hacker News, later deleted but reposted with permission on Marc Bevand's blog, paints a very dreary picture of the state of Windows development. The root issue? Think of how Linux is developed, and you'll know the answer.

This is one of those news items that's fun to write, fun to read, fun to comment on, and where no one will be able to say anything unkind. It's all just one big ball of awesome fluffiness. TuneTracker, the BeOS radio automation software, has just released something very special: TuneTracker System 5, the first version designed entirely and specifically for Haiku. In fact, it actually includes Haiku in the software package. Better yet, TuneTracker also unveiled several system-in-a-box products - which have Haiku and TuneTracker pre-installed.

Exactly twenty years ago, a document was published that played a huge role in establishing the web as we know it today. Twenty years later, and this simple and straightforward document is proof of an irrefutable fact: while closed technologies can change markets, open technologies can change the world.

Oh multitasking. That staple of computing that got thrown out the window with many modern smartphones. We got some rudimentary thing in its place - but even as multitasking on phone and tablets improves, its user-visible side remains cumbersome. Windows 8 has a neat implementation, and now it's time Android follows in it footsteps.

They're here! Whether that excites you or not remains to be seen, but the Galaxy S4, which will most likely become the best selling Android smartphone of the year by a huge margin, has been reviewed by all the major sites, and there's lots of interesting conclusions in there - although I think most of you will get the gist.More Features »

Several years ago, the mediocre Java performance and the lack of good widget libraries marked Java as slow and memory hungry when the first Java applets appeared, most of them based on AWT or 'homemade' widget libraries.
Sadly, these days the myth of Java being slow and memory hungry still remain.
I think if you could compare two current applications running inside the webbrowser, one made with the latest Flash release and the other one using JavaFX running on top of the latest JVMs, the performance would be comparable or, probably (I'm just speculating here) would be better in the Java side.
