There is still no word as to which license it will be released under. For those who haven't seen it yet, Sun has previously opened a public developer community site for soliciting feedback and providing updates about the process."

Will Sun Open Source Java? 700 comments
capt turnpike writes "According to eWEEK.com, there's an internal debate going on at Sun whether to open-source Java. (Insert typical response: "It's about time!") Company spokespersons have no official comment, as might be expected, but perhaps we could hear confirmation or denial as early as May 16, at the JavaOne conference. One commentator said, "Sun should endorse PHP and go one step forward and make sure the 'P' languages run great on the JVM [Java virtual machine] by open-sourcing Java." Would this move Java up the desirability scale in your eyes? Could this be a way to help improve what's lacking in Java?"

It's part of the easing of license restrictions that currently make it difficult to incorporate Java in certain types of Free Software project, and that cause hassle for companies like RedHat and Novell/SUSE who sincerely want to distribute Java but more than that want their operating systems to be 100% Free Software.
It's funny. The prime difference between Open Source and Free Software is that OSS is married to a community based development model whereas Free Software is just the basic principle of it being Free. Everyone keeps using "Open Source" here, but Sun has, actually, been following the community based development model part of Open Source for years without making Java Free Software. If it's not Free Software, it's not Open Source, but Java's certainly proven you can have the advantages of Open Source without actually making your software open source.
So why are they doing this? Well, like I said in my first paragraph, the current license and environment is too restrictive for many significant potential adopters. They're finally recognising people want the freedom, not just an open development model.

I really hope that we can look forward to a working, recent Java version on FreeBSD without the old bugs and the trouble with OSS-principles in the near future. Kaffe / Classpath just isn't doing the trick. I wonder what this will do to OpenOffice.org.
It all depends on the license. I do hope this will draw some of the fine folks at Kaffe / GNU / Apache who have done a great job by recoding Java to Java itself. But then, if it isn't the GPLv3, RMS will probably keep screaming for a "real free" reversed engineered version of Java.
Well then, off to Flash... Adobe?

Cuz really, unless "Java to be Open Sourced" really means "Java to be Open Sourced", it won't make a difference, acceptance of Java will continue to be held back by the perceived closedness of the Java language and real linux-unfriendliness of the Java runtime, and languages like C#/Mono will continue to make inroads until Apache finishes their Harmony project.

Some major things in no particular order:
1. Open Source means Open Source. There's a list of approved licenses. Sun are aware of this, they participate in the OSI, they've submitted licenses before for approval. They're not saying "Open Source" when they mean "Shared Source" or anything like that. Who do you think they are, SGI? ;-)
2. Jonathan Schwarz has specifically stated that the GPL is under consideration. (See his blog) It sounds like they're interested in GPL3 but obviously want to see what it has to say first.
3. OpenOffice.org is available under the GPL. Releasing Java with a compatible license would help resolve some of the issues there are in integrating Java code with OOo code, which is a live issue right now.
4. This is a major issue. Right now, the two major enterprise distributions, RedHat, and SUSE, are promoting alternatives to Java, be they attempted workalikes like GCJ or full blown rivals like Mono. Both RedHat and Novell are being clear on this: they don't want Java in its present form because it's not Free Software. Sun has to act. They're saying they're going to act. This is, stategically, one of their most important projects, if not their most important (Solaris wasn't, StarOffice wasn't even close. By comparison, Java is something dear to Sun's heart as the only technology they own that truly does influence the direction the entire computing industry is going in.) So you can't blame them for taking baby steps. But when they say it's going to go open source, I believe them. And when Schwarz talks about the GPL and uses phrases like "Free Software" and "Open Source" with fairly clear deference to their supporter's meanings, it's hard for me to believe they haven't done their homework, that they're not aware of the damage they'll do if they don't follow through, and that they have no intention of following through.

The more I look at your post, the more I realize you are straddling two fences. You say drop Swing and AWT implying that you are on the server in which case, your not downloading the JVM & libraries to the client anyway. Then you say Java needs to be like a Java Web Start install, meaning you are on the client side and therefore need the libraries you just said to toss! Oh and btw, Java Web Start is part of the jre download - if you have to download and install something to the client, why not download it all at once?

Exactly. Free Software has plenty of JVMs and compilers. Heck, the Free Software world has too many JVMs and compilers. What's needed are Java compatible class libraries under a license that is both amenable to proprietary and Free Software developers.
At this point Sun is simply trying to draw support away from the various Free Java implementations. Sun knows that if the Free Software implementations ever become popular that its chances of controling Java long term are essentially flushed down the toilet. Sun reacted too late with Solaris, and it is desperate to keep Java from suffering a similar fate. So it is doing everything in its power to keep people away from Free Software Java-alike systems.
If Sun were serious it would A) concentrate on releasing the Java class libraries, and B) it would have given Java developers some guidance on the license that it will be using. Everything else is just fluff.

And ARM Jazelle bytecode specs ... ? (Score:3, Interesting)
There are a lot of embedded CPUs that have "Java Acceleration" built in. I'm specifically concerned with ARM's Jazelle -- as found in ARM926ejs CPUs like the one in the Nokia 770, for example, and all ARM v6 CPUs -- but there is also Atmel's new AVR32 (Linux port is in the MM tree) and there are a few other processors that do the same thing.
But you can't get specs on how to use that stuff ... and if you ask the
chip vendors, the answer is that it's Sun's fault. To get specs, you must
sign agreements with Sun. That's for basic stuff like how to preserve the
relevant processor context, and how to enter or exit the "execute Java bytecodes"
CPU mode, and of course exactly what bytecodes exist. (They just accelerate
the bytecodes ... some things need to punt to runtime code.)
What that means is that for example GCC can't use that CPU acceleration by having its Java runtime (GCJ/GIJ) build on it ... one assumes that this
means a performance penalty for at least the bytecode interpretation parts
of almost every Java runtime environment, though
of course it would be interesting seeing how things like HotSpot affect the
performance numbers. (The CPUs that have Java bytecode acceleration are by
the way not ones that normally have big CPU caches, high clock rates, or
very much memory to waste on the stuff HotSpot does.)
So my question: Is this "Open Sourced Java" going to cover ARM's Jazelle? And the AVR32 Java acceleration? And other chips?
Or is it going to be the same-old, same-old? Folk working with embedded systems want to know... the big system bloatware that that Sun ships is not especially useful. Finally loosening the reins on the bytecode acceleration hardware would be a much more useful step.
