JDK 7 Milestone 4

The JDK 7 Milestone 4 builds are now available for download. This was the fourth of eight scheduled milestone cycles. The key new features introduced in this cycle were:

The update to the XML stack was scheduled for M4 but unfortunately couldn’t be completed in time; we hope to see it in M5.

There are of course many other fixes and improvements; the complete list is available here.

Thanks.

I always assumed JSR 305 will also be in JDK 7. Is it not planned to include that?

Excuse me for not quite keeping up with the state of affairs here, but your "JDK 7" text links to the OpenJDK site - so is it safe to assume that the source tags from which these JDK 7 builds were made, and all the daily development of JDK 7 leading/following those builds, can be tracked through the public OpenJDK 7 Mercurial repository then?

The statement regarding the new Java Plug-In makes me happy, because I assume that means that the OpenJDK 7 project now also contains the source code for this, as promised earlier ( http://blogs.sun.com/darcy/entry/openjdk_and_the_new_plugin )?

Thanks for all the great work!

A matching IcedTea7 release is in the works... :)

Hi Mark,

What is the current story around the New Java Plugin? Joe Darcy said Sun was committed to open sourcing the Sun Java Web Start implementation and the new plug-in implementation for NPAPI capable browsers
http://blogs.sun.com/darcy/entry/openjdk_and_the_new_plugin

But later he claimed "circumstances had changed" without explanation what these circumstances were and why they had changed. Could you provide any updates about the current situation and whether or not Sun is still committed? Or should we be promoting the free IcedTea replacements more?

It is one of the last components that sets proprietary JDK apart from the free community OpenJDK.

Thanks,

Mark

Lars: At the moment there's no plan to include JSR 305 in JDK 7, but I'd be happy to consider a specific proposal for doing so.

@Chris: Sorry to be the one to tell you this, but the builds Mark references are proprietary builds. While the majority of source code is taken from OpenJDK7, the plugin is still not part of this. Nor is Java Web Start. I assume they also still use the old proprietary graphics renderer.

Assuming this is the template for the final JDK7 builds from Sun, then there will only ever be proprietary builds from them.

The reason I commented about the IcedTea7 release is because this will be a build of milestone 4 based completely on Free software. It will include the source code that forms OpenJDK coupled with the IcedTea plugin implementation. If you want a Free plugin sooner rather than later, then you are better placed testing this implementation and reporting any bugs than pleading with Sun for them to release theirs. Believe me, we've tried for the last two years :)

Mark: Thanks. I gave a tweet to William Pugh (wpugh) with this link not sure what his plans are.
