The speed test applet here: http://www.thinkbroadband.com/speedtest.html has never worked for me using IcedTea, but did with Sun Java.

My old internetbanking website wouldn’t work with OpenJDK when I last tried. Don’t know if this is still the case, but will give it another shot some day.

I compared the speed of the SUN Java 6 JVM with the one of OpenJDK6 and for fun with the executable produced by gcj.
For that I used version 0.7-009 of my Go program (http://www.vanheusden.com/stop ).

SUN Java6 JVM:
user 0m8.630s
user 0m8.800s
user 0m8.640s

OpenJDK6:
user 0m9.260s
user 0m9.800s
user 0m10.580s

executable:
user 0m19.150s
user 0m19.390s
user 0m19.130s

I must also say that when I used openjdk in jaunty I had major performance issues which were gone with the sunjdk. I’m a professional java developer and can not use openjdk till those performance issues are handled.

Webex won’t work with openjdk either.

Hi,

the applet on this site don’t start correctly with openjdk. Instead with sun-java it’s ok.

In Mexico the taxes online system depends on Java applets. The only Java plugin which works is the Sun one. The reason is the Tax Authority bought a SSL certificate for it main comain sat.gob.mx, nor for its subdomains. In the IcedTea implementation it is not possible to grab and authorize a non valid domain cerificate as reportecero.sat.cob.mx as easy as with Sun Java VM. That operation is not documented and require the writting of obscure rules which are not in the common user knowledge. So, for the mexican users and in order to facilitate the adoption of Linux in Mexico (the taxes issue does not admit any discussion or ideological points of view) the only solution is to using the Sun VM, because the lack of a very simple usability mechanism in the Open Source solutions.

HP’s iLO remote console doesn’t work with openjdk. Together with the juniper blob of fail already mentioned (ncui), that forces me to use Sun’s java.

JDownloader http://jdownloader.org/ does not work with openjdk. When I try to start it, I get

libmawt is installed:
ls -lh /usr/lib/jvm/java-6-openjdk/jre/lib/i386/xawt/libmawt.so

So I still have to use that proprietary sun-java :/

Does Sampopankki web banking work with the open Java solutions? http://www.sampopankki.fi/en-fi/Personal/eBanking/Support/CheckPC/Pages/TarkistaTietokoneesi.aspx If not, then there really is no alternative to Suns Java. I hope someone adopts the orphaned Sun Java, because without it several Linux users in Finland and Denmark are going to end up being really, really frustrated, including my sister, whos computer I recently upgrade from Windows2000 to Ubuntu Hardy just recently.

I just tried uninstalling sun’s and installing openjdk as suggested.

This applet doesn’t run with openjdk: http://byenspuls.dsb.dk/byens_puls/ByensPuls.html (it shows a live, moving map of trains in Copenhagen.)

I get this output:
../IcedTeaPlugin.cc:3890: Error: create process
../IcedTeaPlugin.cc:1667: Error: started appletviewer

(firefox-bin:7760): GLib-CRITICAL **: g_io_channel_write_chars: assertion `channel != NULL’ failed
../IcedTeaPlugin.cc:4103: Error: Failed to write bytes to output channel

with the last two lines repeating over and over again. Worse, the login-applet that my bank uses doesn’t work either, so that is a show-stopper.

I tried moving ~/.java/ but that didn’t make any difference.

I hope this counts as direct technical evidence you can reproduce, otherwise let me know what I can do to provide better information.

Thanks!

I have had much the same experience with OpenJDK, and it seems to have gotten even better over time, as should naturally be the case (or so one would hope). Anyway, I’ve been a long time user and get along just fine.

The software from Cleversafe does not work with OpenJDK, nor does pogo.com. Don’t make fun of me, I am addicted to winning money on pogo.com and playing some really neat little games from time-to-time :p I have a couple of projects I am consulting on that don’t work with OpenJDK currently, though I am trying to get them to work.

Here’s a bug that causes every Java application that uses Rhino to break when used with OpenJDK: https://bugs.launchpad.net/ubuntu/+source/openjdk-6/+bug/255149

The bug is over 1 year old, and affects a lot of the tools I use on a daily basis (such as YUI Compressor).

Lots of comments! While it’s good to see a list of stuff people are claiming don’t work, I’d still like to see bugs opened for the errors. Without a way to track down the actual causes, it’s hard to progress. I’m also curious about another class of issues, just touched on lightly above: regressions in performance — that’s a very different issue too.

There’s a bit more to a Java Runtime Environment (or Development Kit) than just running applets in the browser.

Thank you for making this article, I myself did not know that java6 was depreciated/being depreciated in the near future by Sun! I have since removed java6 and installed openjdk in its place, and it works like a charm.

By: Andrew

Andrew — Sat, 12 Sep 2009 22:39:51 +0000

If you do the install before doing the remove then apt won’t try and remove every package that depends on a (no longer present) jvm.

Thanks for the tip!

1.After installing Jaunty, I installed Eclipse with apt-get. The code completion was just horribly slow, untill I switched to sun-java6.
2.Alfresco (opensource document management server) does not work with openjdk.

Interesting, I haven’t had any Java runtimes and/or plugins installed since I last reinstalled Debian on my laptop, a few months ago, and I’ve only just realised. I guess Java still hasn’t pushed its way into the “essential” category for me. Thanks for the heads-up, though.

9.10(a4): The last time I checked to remove sun-java6-bin, I saw a dependency of Open Office. Is that gone?

Oh… I should have mentioned that it worked in the past (< 9.04) with at least firefox. With epiphany it never worked for me.

Hi,

you want a failure… you will get one :-)
–> The network-connect vpn-client from Juniper (ncui-1.2-1) does not work with openjdk. With sun-java it does.
Pretty funny is that it in 9.04 neither with epiphany nor firefox works. I had to install opera to get it to work at all :-/
