Bug Reports For Non-Sun JDKs Not Accepted

[Fred]

If you want to provide a compatibility fix for openjdk, that's great, but don't complain if it doesn't work OOTB on openjdk...

OLV officially needs to be run with sun JDK 1.6.0 or above. It will probably work with 1.5.X JDKs too, but I'm unsure about that. I'm unsure if 1.7.X has been tried or not, however I would expect it to work without issue in 1.7.X. Please post if you can provide reports on these uncertain cases.

If you have issues and are not using a fairly recent JDK from sun/oracle, please fix that situation before bothering the developers, or fix OLV, without impact on users of the supported versions, and provide the fix for inclusion.

Oracle recently decided to remove the DLJ (Operating System Distributor License for Java) from their license on their own proprietary implementation of java. Basically, this means that Linux distributions will not be able to package new releases of the proprietary JVM/JDK. The only release available in the Linux distributions will be the OpenJDK.

Is it going to be better in the long run to be supporting OpenJDK in OLV?

[Fred]

Certainly seems like it, but the opposite is how it should be worded. In the long run OJDK will be bug free and support us :-)

I think the emphasis should go on reporting issues to OJDK, so by all means, use it, but still, complaining to us is the wrong choice. Send the bugs upstream and the work-arounds to us :-)

[Fred]

It would appear that OJDK works just fine, so I'm unstickying this until it gets bumped with some specific information.

Just ran a new app for the first time, and it said this:

WARNING: You are launching the IDE using OpenJDK Java runtime.

ITS KNOWN TO HAVE PERFORMANCE AND GRAPHICS ISSUES!
SWITCH TO THE ORACLE(SUN) JDK BEFORE REPORTING PROBLEMS!

Also, BTW, someone I was talking to recently mentioned some performance issues on Mac OS X when using Oracle JDK 7, which didn't exist in the Apple version. It was a GUI thing, so presumably the Apple native interface was/is better. Just FYI.

This version:

Code: Select all

OpenJDK Runtime Environment (IcedTea6 1.12.4) (6b27-1.12.4-1)

Has at least three Swing bugs that I've found so far.

However this version:

Code: Select all

OpenJDK Runtime Environment (IcedTea7 2.1.6) (7u3-2.1.6-1)

Has none of them.

I just added Oracle JDK 6 update 43 to my development box and it works fine too. IE, all three bugs are not present in it.

Yuck:

Product Registration is FREE and includes many benefits:
* Notification of new versions, patches, and updates
* Special offers on Oracle products, services and training
* Access to early releases and documentation

Product and system data will be collected. If your configuration
supports a browser, the JDK Product Registration form will
be presented. If you do not register, none of this information
will be saved. You may also register your JDK later by
opening the register.html file (located in the JDK installation
directory) in a browser.

For more information on what data Registration collects and
how it is managed and used, see:

Ari reported to me that Java 7 from Oracle causes machine lock up of some type on full screen. Key board input can not get you out, you're screwed. He also said that performance of animation was poor in Oracle Java 7. He has an Apple Java 6 installed too, much like the one I have on my macbook air, and the same software full screens fine and animates better on that. So, if you're on a Mac, bug reports not accepted unless you're running Apple's JDK/JRE...

Get it here: http://support.apple.com/kb/DL1572

Ari's OS is 10.7.5 and his Oracle variant was 17.

Another notch in the belt for OpenJDK: Running some unit tests here, I get a PermGen error with Oracle and perfect smooth performance with OpenJDK. IE, Oracle JDK is completely unusable for this task! :-o

Also, newer OSX versions pull in oracle by default, I think. Unsure if it works OK or not, but seems like it at least mostly does from what I hear.
