Kelly O'Hair: OpenJDK Bug States

2008-05-11T19:25:49Z

Until the OpenJDK project converts to Bugzilla, I thought some more information about how our internal bug tracking system works might help people watching the current situation.

John Rose: the golden spike

2008-05-10T20:24:44Z

In the Java cosmos we can reckon time in terms of JavaOne conferences. For programming languages on the JVM, the just-finished epoch has seen much progress, and the next epoch looks even better. Here is some of the progress that I am excited about, after bouncing around at JavaOne... ...

Kelly O'Hair: ZZ Top

2008-05-10T20:01:20Z

Last night we drove to Dixon, California and saw the legendary hard rock band ZZ Top.

James Gosling: Too much fun...

2008-05-10T05:44:37Z

My keynote this morning went off flawlessly. You can watch it on UStream. I'd like to thank everyone who contributed: The demos were all incredibly inspirational. I was in awe of every one of them. The main hall at Moscone was packed. The production crew was totally perfect, despite all the re-arranging of the plan. And the Sun crew were their usual wonderful selves. ...

Cay Horstmann: Java One Day 4

2008-05-10T02:51:24Z

Day 4 of Java One is over. Even without huge announcements or great surprises, it was a great conference. Here are my impressions from the cool stuff keynote and my takeaway what it all means.

A. Sundararajan: Thursday May 8, JavaOne

2008-05-09T15:26:14Z

Here are the few highlights from the talks that I attended today:

James Gosling: Aiee!!

2008-05-09T13:26:17Z

I don't know how some people manage to blog so much. Yesterday was another huge blur. A big chunk was rehearsing for my keynote this morning. It's kinda easy for me because it's mostly demos, and they're all wickedly cool. We added a new one late last night because some folks got something to work that was pretty magnificent. Drives the stage crew mad. ...

Gary Benson:

2008-05-09T12:25:55Z

Well, it’s taken a month and a half — and over 2000 lines of code — but I finally got a method out of Shark. I made a chart showing which bytecodes are implemented, which I’ll keep updated as I progress. The estimated total coverage of 18% is slightly fanciful as it treats all bytecodes [...]

Mark Wielaard: The GPL is like a green envelope

2008-05-09T10:24:46Z

German court tells Skype to obey the GPL: “If a publisher wants to publish a book of an author that wants his book only to be published in a green envelope, then that might seem odd to you, but still you will have to do it as long as you want to publish the book and [...]

Jeroen Frijters: Compiler Intrinsics

2008-05-09T09:27:51Z

Most compilers have some (or in some cases many) intrinsic functions. HotSpot has a number of them (see here, search for "intrinsics known to the runtime") as does the CLR JIT. IKVM has had a couple as well (System.arraycopy(), AtomicReferenceFieldUpdater.newUpdater(), String.toCharArray()). These were sort of hacked into the compiler and I finally decided to clean that up a little and add more scalable support ...

Cay Horstmann: Java One Day 3

2008-05-09T06:57:53Z

James Gosling: Wednesday at JavaOne: what a ride!

2008-05-08T15:40:29Z

Yesterday was totally packed. Absolutely no rest for the wicked :-) Lots of great interactions with all sorts of folks, some in organized meetings, but most just random chats in the hallways. I love the energy that is everywhere. ...

Cay Horstmann: Java One Day 2

2008-05-08T15:28:08Z

Here is my report from day 2 of Java One. I continue to feel diffident about RIA and Java FX Script, the theme of this year's Java One, so I decided to make my own themes: Ease of development, and transparency.

A. Sundararajan: Wednesday May 7, JavaOne

2008-05-08T14:58:58Z

Today Bill, Chihiro, Jaya and I talked on Blu-ray. The talk was centered around the open source project @ http://hdcookbook.dev.java.net - a library and a set of tools to build Blu-ray discs. If you haven't checked out code/docs, you may want to checkout and play with the code. All you need is a laptop with blu-ray drive and a BD-RE disc. Optionally, for added fun you ...

John Rose: dynamic invocation in the VM

2008-05-08T06:59:00Z

For several years now, JSR 292 has promised an invokedynamic instruction in one form or another. The problem has been with picking the one form that simultaneously enables a good range of use cases, addresses several architectural challenges in the JVM, and can be optimized by a variety of commercial JVMs. It has been a restless search for “one bytecode to rule them all”. ...

Kelly O'Hair: Sun Studio Compilers on LINUX?

2008-05-07T19:47:39Z

With the magic of Mercurial, you can see changesets, like this one: http://hg.openjdk.java.net/jdk7/jdk7/hotspot/rev/485d403e94e1. Which Serguei Spitsyn integrated recently.

Kelly O'Hair: InfoQ Article on Git, Mercurial, and Bzr

2008-05-07T19:18:58Z

As some of you may know, we've made changes recently to the KSL project that was started last year.

Andrew Hughes: More on rms

2008-05-06T21:25:31Z

So I went to the rms talk last Thursday and throughly enjoyed it. This was the second time I’d seen him speak, and can certainly recommend it to others. As others have remarked, he is quite entertaining to listen to and the way he upholds and adheres to his values is worthy of [...]

Daniel Fuchs: Mapping to OpenTypes: MXBean Complex Attribute Types

2008-05-06T15:37:15Z

Although it might not be a very good idea to define your management model based on how it will be displayed by a given GUI, such as that provided by JConsole or VisualVM, I believe it is nonetheless interesting to explore the various ways in which a complex type such as a Map<String,Integer> could be modeled and exposed through an MXBean attribute.

Mario Torre: New powerful Gear!

2008-05-06T13:42:02Z

I finally was able to run the Gear demo from Jogl with the Classpath escher peer.

Cay Horstmann: Java One Day 0

2008-05-06T06:22:31Z

Last year, Java One Day 0 was Netbeans Day, in a cozy hotel. This year, the Java One week started much more grandly, with Community One, at the Moscone Center. My mind wandered during the keynote speech, but I was enchanted by the enigmatically named EclipseLink and robots that had cockroach reflexes and were programmed in GreenFoot.

John Rose: interface injection in the VM

2008-05-06T05:01:13Z

“Self-modifying code...” used to be a phrase always uttered (by us hackers) with tones of both admiration and dread. Operating systems and VMs are required to support it (always, in the loader). Aspect oriented programming has made a cottage industry of it. I still fear it, and when I hear customers ask for an API to edit classes in the JVM, I always reach ...

Stephen Colebourne: Enhancing Java - Multi-lingual blocks

2008-05-02T00:45:49Z

The reality for Java is that there are many other programming languages, and many of those have features that Java developers sometimes wish they could access. But its simply impossible to add all those features. Is there a possible alternative if we think 'outside the box'?

David Herron: Open media and open screens

2008-05-01T19:40:23Z

A. Sundararajan: JVM Languages @ JavaOne 2008

2008-04-30T05:24:42Z

In JavaOne 2008, there are many intesting sessions on "other" JVM languages covering both dynamically typed languages (JavaScript, Groovy, JRuby) and statically typed languages (JavaFX, Scala). As usual, there are many sessions covering application aspects -- like using scripting on Glassfish, Grials (Groovy), Rails (JRuby) and so on. But, my interest is mostly on the programming language aspects and JVM implementation issues. Here is a ...

Robert Lougher: Third time lucky?

2008-04-28T15:07:00Z

In JamVM 1.5.0 I released the "inlining interpreter" which copies code blocks together in a similar way to a simple JIT (but the code is compiled by gcc, rather than being generated natively as in a JIT). This achieved an impressive speed improvement and I've been keen to optimise it further.The major thing which has been in my sights is the remaining dispatches ...

Robert Lougher: JamVM : back on the map

2008-04-28T14:35:00Z

I feel like a kid who's thrown a tantrum and been rewarded with an ice-cream. In my last post I really thought I was asking a "serious and legitimate question" but it's difficult not to squirm when you get the praise you were secretly hoping for...So I'm grateful to all those who replied. JamVM is firmly back on the map :)

Joe Darcy: Test where the failures are likely to be

2008-04-26T00:52:18Z

There is a old joke about walking along one night and coming across someone looking down underneath a streetlight for lost keys. Stopping to help look, after a minute or two of searching you remark, "Your keys don't seem to be here. Where did you drop them?" "Well, I dropped them over in that ally, but it's way too dark to look there!"

Stephen Colebourne: Java 7 - For-each loop control access

Robert Lougher: JamVM : road to nowhere?

2008-04-25T16:29:00Z

Change logs and development notes never give any insight into the wider whys and wherefores of a project. Perhaps that's for the better; stick to the facts, that's what engineers are good at. But as this is my first real post on JamVM (now that I know everything is working) I think it's appropriate.I started JamVM because I stopped being paid to work ...

Joe Darcy: Compatibly Evolving BigDecimal

2008-04-22T02:36:57Z

Back in JDK 5, JSR 13 added true floating-point arithmetic to BigDecimal, which involved many new methods and constructors along with new supporting classes in the java.math package. I was actively involved in the JSR 13 expert group and integrated the code into the JDK. These changes had some surprising compatibility impacts which can be classified according to their source, binary, and behavioral effects. ...

Mark Wielaard: Fedora 9 Preview

2008-04-20T14:24:31Z

Been playing with the Fedora 9 Preview release on my laptop this weekend. It feels pretty snappy and the integration of the various new components is pretty smooth. I didn’t find any personal show stoppers. So I will definitely upgrade my main machine as soon as the final release is out (currently scheduled for May [...]

Andrew Hughes: Gentoo and Free Java

2008-04-18T09:09:22Z

Over the last week, I’ve been getting Gentoo and Free Java up and running on my new x86_64 box, a process which has culminated in the creation of my own overlay: http://fuseyism.com/hg/libre_java_overlay For those unfamiliar with Gentoo, an overlay is an additional set of packages (known in Gentoo as ebuilds, as for a source-based distribution the packages [...]

Joe Darcy: Kinds of Compatibility: Source, Binary, and Behavioral

2008-04-18T02:31:38Z

When evolving the JDK, compatibility concerns are taken very seriously. However, different standards are applied to evolving various aspects of the platform. From a certain point of view, it is true that any observable difference could potentially cause some unknown application to break. Indeed, just changing the reported version number is incompatible in this sense because, for example, a JNLP file can refuse to ...

John Rose: method handles in a nutshell

2008-04-17T07:24:02Z

The JVM prefers to interconnect methods via static reference or dispatch through a class or interface. The Core Reflection API lets programmers work with methods outside these constraints, but only through a simulation layer that imposes extra complexity and execution overhead. This note gives the essential outlines of a design for method handles, a way to name and interconnect methods without regard to method ...

James Gosling: Space Junk
2008-04-15T04:26:52Z
Today we got to put out one of the most
weirdly cool press releases that we've
done in quite a while.  It was nice to see some
blogosphere pickup from Tim O'Brien.  Projects like this have quite a rigorous evaluation process to get to the start of deployment.
One of the fun things about the realtime version of Java is that it gets us ...
