Coherence Incubator 11 Released

It’s here!  Oracle Coherence Incubator Release 11 has now been finalized and made public.  Everyone can now pick up the official Maven builds from maven.java.net or via Maven Central.

Instead of repeating all of the goodies and release details again, I’ll simply refer you to take a look at my recent post.   However to save you some time, here are the important new links:

Coherence Incubator Project:
http://cohinc.java.net

Coherence Community Source Code:
https://github.com/coherence-community

Release Documentation:
http://coherence-community.github.com/coherence-incubator/11.0.0/

Downloads:
If you’re not using Apache Maven for dependency management, you can still download the signed artifacts manually, including the jars, javadoc and source from Maven Central (which is http://search.maven.org/) Simply search for: “coherence incubator“.

What about Coherence Incubator 10?
Over the next few days, weeks and months our plan is to retire Coherence Incubator 10.  During this time we will be encouraging everyone to move over to Coherence Incubator 11.   There are a lot of advantages to this (like being able to easily build it yourself).  

Importantly we’ve gone to great lengths to ensure that Coherence Incubator 11 is technically the same as Coherence Incubator 10 – if they aren’t that’s a defect – which we should be able to resolve.  Basically anyone that’s currently using Coherence Incubator 10 should be able to simply swap the jars (updating the versions of course) and carry on.  Of course there are a few differences, but this are scoped to where and how examples are run, together with new documentation.

As we’ve previously done with major releases,  the old site, documentation and downloads for Coherence Incubator 10 will still be available.  We’re not taking those away.   However all new work and defect fixes will only occur in Coherence Incubator 11+ (unless there’s some monumental pressure – and I mean monumental).

Enjoy!

Where’s my Eclipse IDE gone? (into the Trash)

After using and I guess supporting the Eclipse IDE now for almost 10 years, it’s finally failed badly enough that I’ve dragged into the Trash.  Why?  The last straw was simply the irritating and annoying unstable editor scrolling performance on a variety of platforms.  It’s no longer worth it.

eg: Working on my notebook 11″ screen is fine.  Working on a 24″ screen is slow.  Working on a 30″ screen – scrolling just doesn’t work.   Of course the caveat here is that I’ve got white-space highlighting and line numbers turned on.  If I turn these features off it works fine.  However, I need and use these features everyday – hence it’s no longer a solution.

I tried a bunch of releases, patches, hacks, work-arounds and searched the code base.  However  there comes a point in time that trying to resolve the problem is far more painful than switching IDEs.

So I’ve switched.  I switched to JetBrains IntelliJ 11 (and 12).   It wasn’t easy and wasn’t exactly fun (after nearly 10 years on Eclipse there’s a lot of short-cuts to remember), but it’s worth it in terms of productivity.  (While I could use the Eclipse key-mappings, I have no intention on going back so I’m gradually learning the native IntelliJ ones).

Luckily all of my favorite plugins are supported, especially JIndent that I which I use routinely across around six different projects.

So… So long Eclipse.  You were once a great platform.  Now you’re slow, large and cumbersome (compared to other platforms out there).

PS: Buying a personal license of IntelliJ is so worth it!

Coherence Incubator 11 (coming to an open-source repository near you soon…)

As mentioned at the past few Oracle Coherence Special Interest Group (SIG) and Customer Advisory Board (CAB) meetings, we’ve been busily working away at opening up (open sourcing) the entire Oracle Coherence Incubator for the Coherence Community.   I’m very pleased to say that this work is now “almost” complete!

Note: I say “almost” complete simply because we’ve not yet made an official release from the source repositories, but as far as openness goes, the work is now done.

If you’ve been looking at or using the Oracle Coherence Incubator in the past, a lot of things are about to change organizationally.

1. All source code and documentation is now officially licensed under CDDL.

2. The entire project has been “Mavenized”.  ie: easy to build, release etc from source.

3. All source code and documentation is now publicly available on GitHub.  ie: easy to access for everyone.

4. The project is now officially hosted at java.net.  ie: it’s like Glassfish and other open-source Java projects.

5. The issue tracking system is also publicly available (also on java.net).

6. The project documentation is now part of the project source (as a maven site).

7. You can now officially contribute to the Incubator!  Instructions on “how” are in the project documentation

8. Releases will be available on http://maven.java.net (and Maven Central).  Snapshots are already available on http://maven.java.net.

While these are major structural changes to the project, the source packaging and classes remain the same.   ie:  Coherence Incubator 11 is simply Coherence Incubator 10, but cleaned up with a new home and licensing model.

Here are the important new links:

What about Coherence Incubator 10?

Ultimately the plan is to retire Coherence Incubator 10 and encourage everyone to move over to Coherence Incubator 11.   There are a lot of advantages to this (like being able to easily build stuff yourself).

Technically they are the same (if they aren’t that’s a defect – which we can track openly!).  We’ve gone to great lengths to keep them in sync so that everyone that’s been using Coherence Incubator 10 should be able to simply swap the jars (updating the versions) and carry on.

Once we’ve made an official release of Coherence Incubator 11, we plan to retire Coherence Incubator 10.  The site and downloads will still be available.  We’re not taking that away.   However all new work and defect fixes will only occur in Coherence Incubator 11 (unless there’s some monumental pressure – and I mean monumental).

Currently Coherence Incubator 11 contains a rollup of all changes to Coherence Incubator 10.  ie: in terms of source code they are the same (or very close).

So if you’re using Coherence Incubator 10, take a look at Coherence Incubator 11.  Grab the snapshots from maven.java.net or build it yourself from GitHub.

What’s next?

There’s still a bit of documentation to move over from Coherence Incubator 10 site and into Coherence Incubator 11.  We’re hoping to have this completed in the next week or so.  After this we’ll start the process of making an official release.  Once this is complete, we’ll announce retirement plan for Coherence Incubator 10.

As you can guess by the time this has taken, this has been a massive effort.  While it may seem like it was a simple project restructuring  – eg: getting source, documentation ready, this has involved a tremendous amount of organizational and community consultation.  I’m happy to say we’re through this now.   I look forward to putting out some new releases with new functionality pretty soon.
