For what it's worth, there's a big difference between earlier and later OpenJDK versions - the earliest versions had a lot more differences from the Sun/Oracle codebase than the newer ones. I don't recall at which point this changed, but current versions certainly work fine...

To all pointing out that I indeed can play Minecraft with OpenJDK ... I will try it next time but also judging from the tutorials lengths it is not as straightforward. Last time it was a major disappointment and I tried literally everything to NOT install the official JVM blob. Unfortunately at end of the day I wanted to simply play the damn game so I yielded. :-)
Anyway, I am in favor of OPEN competing technologies so if Java/JVM can be open that I am good with that (but the applets must go).
What tutorials lengths are you talking about?
On a Debian based system, run as root:
Then double-click on minecraft.jar and it should just work if you installed your graphics drivers properly. If you can't run it by double clicking for whatever reason (depends on your desktop environment), you can run in the terminal:Code:apt-get install openjdk-7-jre
in the folder where the minecraft jar is located and it should run.Code:java -jar minecraft.jar
I can independently confirm that it works fine with Minecraft:
the game ran flawlessly. I only played for a minute or so.Code:sudo apt-get install openjdk-7-jre cd ~/opt/minecraft /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java -jar minecraft.jar
I do remember older versions of OpenJDK being not as good as the official releases. Obviously, the recent 7+ OpenJDK builds are much more similar to the official release.
