IndioMan writes "IBM is releasing an SDK for Java 6 and is sponsoring an Early Release Program to gather feedback from the Java community. Product binaries and documentation are available for Linux on x86 and 64-bit AMD, and AIX for PPC for 32- and 64-bit systems. In addition to supporting the Java SE 6 Platform specification, IBM's SDK also focuses on platform stability, performance, and diagnostics. It's tops on every benchmark."

I do, except I run a 32-bit firefox that I install by hand because I need a java plugin that works. You have to remove the barriers before people will use it, and once you do remove the barriers, they will come.

There are 2 ways to get a 32-bit Java plugin running under a Linux/AMD64 environment (BTW, AMD64 is the official arch name implemented by AMD and Intel, x86-64 has been officially abandonned):
Of course, since Sun has open sourced Java, a 64-bit Java plugin is likely to appear soon.

Higher scores are better. Both run on AMD X2 5000+
Sun VM stomped on IBM's. That wasn't true with earlier VM's. IBM used to smoke Sun on scimark. Maybe there's more development to be done.
Where are the sources ? (Score:3, Interesting)
SUN has released the sources to it's compiler and JDK.

Those benchmarks are based on Java 1.5, too. 1.6 is even faster.

Because this is slashdot, and perl is one of the Chosen Few Languages, along with C, Ruby, Python and PHP. Java, being both closed (for the moment) and slow (5 years ago on the client side) is not. Therefore, any statement that compares Java favourably with one of the Few Chosen Languages must be either a troll or flamebait.
It's easier when you stop fighting the groupthink.

It seems to me that once Java is opened up and is included with every Linux distro out there, Java will not be perceived as large and slow anymore. It will be a simple apt-get, yum, etc away. It will just work.

Are your "write once, run anywhere" applications using internal APIs, or are they relying on bugs in the 1.3 class libraries to run? Personally I've only ever come across code that DOESN'T run properly on 1.3, due to bugs introduced between 1.2 and 1.3, and fixed in 1.4.
Re:The Fastest JDK? (Score:5, Informative)
There could be several reasons why Java 1.3 code won't run on 1.4. One is if you use sun.* or com.sun.* packages directly, which is funcamentally against portability guidelines. Another could be real incompatibilities. There are very few incompatibilities between 1.3 and 1.4. They are listed here:

If you keeping customers from using Java 5.0 or Java 6.0 because you can't sort this out, you are keeping them from major performance and functional improvements.

Sorry, but I don't believe that. You probably have problems to run 1.4 java on a 1.3 VM
1.3 byte code must by definition run on a 1.4 machine, and if there is indeed a problem in the class libraries a simple look at the exception trace should show you where. Even if

I think you're wrong. Even today, over 15 years since Java was first announced, we see little use of it for client-side development. There are only a handful of consumer-grade applications written in Java, with the most popular being Azureus and RSSOwl. Even then, one of the chief complaints against them is their lack of responsiveness and their excessive memory consumption. And keep in mind that they use SWT for their GUIs, which is in fact far lighter and more r
