I rapidly looked around the forum see if anyone had a similar issue and I didn't find anything, I apologize if this has already been solved.
I recently installed Fedora 16 after having lost patience with Ubuntu. Yesterday, after having messed up the graphics driver update (due to stupidity) I reinstalled the operating system, so this is a relatively fresh install.
After having played the game Minecraft a few times without any notable issues, I then installed Libreoffice writer (libreoffice-writer.x86_64) and Libreoffice Impress (libreoffice-impress.x86_64). After this install, Minecraft no longer runs sucessfully.
I get the following error message in the terminal when the game stops loading and gets stuck on a black screen:
Exception in thread "Minecraft main thread" java.lang.UnsatisfiedLinkError: /home/edward/.minecraft/bin/natives/liblwjgl.so: /home/edward/.minecraft/bin/natives/liblwjgl.so: wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch)

I run the latest Oracle JRE version 6 update 30 downloaded from their website (I downloaded the linux 64 RPM file). Nothing else was done on the machine except install the two Libreoffice programs, and if I remember correctly they also use some aspects of java (correct me if I'm wrong).
I'm not sure where to look to find an answer to this. What happened, and how is it possible to reverse it or fix it?
Thanks for your patience and help.

After lots of fiddling around, I have managed to get it working. This is how I did it (if anyone ever has the same issue as me):
Although I had successfully installed Sun's JRE version 6 update 30, Fedora was still relying on the OpenJDK Runtime Environment, which I found out by typing:
$ java -version
I therefore had to use the alternatives
command to install Sun's Java Runtime Environment properly. I typed (in root)
alternatives --install /usr/bin/java java /usr/java/default/bin/java 3
alternatives --config java
There it allowed me to select the java version that would run (I selected the one in /usr/java/default/bin/java). To confirm this worked, it should say something like:
java version "1.6.0_30"
Java(TM) SE Runtime Environment (build 1.6.0_30-b12)
Java HotSpot(TM) 64-Bit Server VM (build 20.5-b03, mixed mode)
From then, I ran minecraft.jar as usual and the error message was gone, game works.
I guess this is one further step in understand the wonders of Fedora and Linux. Hope this will help other people who are as clueless as me.
