Hello all, I'm trying to get Minecraft working on my computer.

I'm running FreeBSD 8.1-amd64 with the latest NVidia driver and Sun Java:

[nicole@Emi#Desktop]java -version
java version "1.6.0_03-p4"
Java(TM) SE Runtime Environment (build 1.6.0_03-p4-nicole_17_aug_2010_02_15-b00)
Java HotSpot(TM) 64-Bit Server VM (build 1.6.0_03-p4-nicole_17_aug_2010_02_15-b00, mixed mode)

When I run the game and try to log in, I get this screen and console output:

[nicole@Emi#Desktop]java -jar Minecraft.jar
Username is 'okeeblow'
java.lang.NullPointerException

Any help would be appreciated, since search didn't turn up anything

[boran_blok]

your java is outdated. you have "1.6.0_03-p4" and the latest is "1.6.0_21-something"
go to www.java.com and update your java first.

[okeeblow]

That's the newest version that's in Ports, unfortunately. Does anyone have any experience with OpenJDK and Minecraft? Google is returning conflicting reports of success and failure with that.

[boran_blok]

OK ignore whatever advice I was giving. Did not notice that you were talking about a FreeBSD config.
The evrsion I mentioned is the latest windows version. I do not know how synshconized the version numbers are over different OSes

[ns]

I can confirm this. Identical error on FreeBSD 8.1-STABLE w/ Sun JDK (same JDK & port version OP is using.) Using the windows version via wine gets further than using the jar, even (though it isn't playable.)

The error occurs after logging in, when the game attempts to update files.

[n44777]

Can confirm this as well. FreeBSD 8.0 amd64 with Oracle's OpenJDK 6 and 7 (corresponds to 1.6 and 1.7, respectively).

[okeeblow]

Using OpenJDK6 instead of sunjdk:

[nicole@Emi#Desktop]java -version
openjdk version "1.6.0"
OpenJDK Runtime Environment (build 1.6.0-b20)
OpenJDK 64-Bit Server VM (build 17.0-b16, mixed mode)

Yeah, definitely. I've had to apply similar ipv6 workarounds for other programs (not just on FreeBSD).

[qualal]

ns: when you said the game was not playable under wine, did you mean similar to what I experienced in virtual box? (see below)

Virtual box will run the minecraft but gameplay is woefully bad. Any attempt to move is so laggy that its virtually impossible not to overshoot by miles every time you want to look at something or move somewhere. Either that, or you play the game as if you are controlling the mars rovers and wait 10 seconds after every keystroke/mouse move before contemplating the next.

When trying to play minecraft natively, I have the same problem as everyone above, I am running PCBSD 8.1 (FreeBSD 8.1, KDE 4.4.5) I am also running Java Platform Standard edition version  6 update 7 (build 1.6.0_07-b02)

I can't run the game from the .jar file and I can't launch it in opera or firefox either!

Has anyone managed to get the game running in a browser despite it not working from the .jar file?

For the record here is what happens when I try the jar file:

java minecraft.jar

which results in:

java Minecraft.jar
Exception in thread "main" java.lang.NoClassDefFoundError: Minecraft/jar
Caused by: java.lang.ClassNotFoundException: Minecraft.jar

        at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:319)


I get the Fatal Error Occurence (2) message when trying to run the Minecraft.jar file via the following command recommended by the website:

java -Xmx1024M -Xms512M -cp Minecraft.jar net.minecraft.LauncherFrame

and after entering login details I got

        at net.minecraft.Launcher$1.run(Launcher.java:73)

When I try to run the game via browser I get the game name at the top of the page and nothing below it (except for the same background pattern the website has).

Has anyone at all made progress on getting this game to run under BSD?
Can anyone help me get it going on ANY browser (I would even gladly install IE if it worked on that)?

[ns]

qualal: Via wine, the files update, but the title screen never comes up for me. The program just hangs after updating.

I can't help with you with browser-based play. Sorry.

I am now of the belief that there is a specific dependency on the string 'Linux' *somewhere* prior to files being updated,  which of course will fail on a FreeBSD system.

I can run a minecraft server with no problems on the same box.

I'll do some more digging and see if I can figure out where the null pointer is coming from.

Update:

Little bit of a guess, looks like it's calling the Unpack method and passing a variable that's got a null value. I'm guessing that because I don't see the program try to download any files, it's messing something up during download, and when it goes to unpack, the file isn't there.

[jandrese]

I think this is the offending code:

		String osName = System.getProperty("os.name");
		String nativeJar = null;
		if(osName.startsWith("Win"))
			nativeJar = "windows_natives.jar.lzma";
		else
		if(osName.startsWith("Linux"))
			nativeJar = "linux_natives.jar.lzma";
		else
		if(osName.startsWith("Mac"))
			nativeJar = "macosx_natives.jar.lzma";
		else
		if(osName.startsWith("Solaris") || osName.startsWith("SunOS"))
			nativeJar = "solaris_natives.jar.lzma";
		else
			fatalErrorOccured((new StringBuilder("OS (")).append(osName).append(") not supported").toString(), null);

I'm not sure exactly what's going wrong (is System.getProperty("os.name") broken on FreeBSD)?  It's not spitting out the error I expected, but I'm guessing something in there is returning a null and causing the program to crash before it gets to the fatalErrorOccured at the bottom.  The whole thing is in a try/catch block to Exception.  Exception just calls the stack trace function and then returns (which is why the stack trace is printed twice, the fatalErrorOccured function also calls it.

[Oxyd]

I just want to note that Minecraft runs just fine for me under FreeBSD using the Linux Java binary. That is, under linuxulator.

I installed linux-sun-jre-1.6.0.03 from Ports, and created this script:

#!/bin/sh

export JAVA_HOME=/usr/local/linux-sun-jre1.6.0
java -jar Minecraft.jar

And I can now play Minecraft on FreeBSD by running this script!

[dextro_]

Oxyd could you do me a favor and try and run the minecraft server? I am getting a new dedicated server and really wany FreeBSD but if I can't host a MC server on it I am going to go Arch Linux.

[jandrese]

FWIW, the Linux-sun-jre16 port got further for me, but still failed to actually start the game.  This time it took the login, downloaded the .so files, but then failed to link them in for some reason:

Looking at the directory, it seems that those .so files are there, so I'm not sure what the problem is.  It did barf earlier on not being able to find 'javaw', but I'm not sure if that is important or not.  

Exception in thread "Minecraft main thread" java.lang.UnsatisfiedLinkError: Can't load library: /home/jandrese/.minecraft/bin/natives/liblwjgl.so

        at java.lang.Thread.run(Unknown Source)

Update: I tried linking java to javaw just for the heck of it.  Now the game doesn't spit out errors, but the script exists with just "Killed", suggesting a segfault or something.  Interestingly, the login window thread stays running, so I can send my name and password, but when I hit login it flashes up a loading screen for a split second, then just black.

[jandrese]

Also, the minecraft server works fine for me in FreeBSD.  

I start the server with

#!/bin/sh

java -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui

Clients are able to connect normally and it seems to run fine.  It's a bit more resource intensive than I expected, but as I understand it that is normal.

[okeeblow]

Oh yeah, I had success with linux-sun-jdk16 a few months ago. Sorry I forgot to post here about it.

[floydoss]

just wanted to know, i also get this error on windows 7 minecraft but i have fully updated java and reinstalled it and my drivers r up to date i would like to get some help with this?

[NalydRelwof]

I am also having these issues with PC-BSD 8.2 "Hubble".  I have a couple questions about your procedure, did you first remove your BSD version of Java?  Second, how would I go about installing the Linux version from Ports (I am new to BSD from Linux)?  This is probably a dead thread, but any help would be appreciated.

BTW: Floydoss, I don't think you'll find help on a Windows problem on a BSD thread, especially one that seems to be dead.

Edit: I am encountering jandrese's problems, and in a PM he stated that he has had no luck in solving them.

[bgalakazam]

By the way, while the devs are too busy getting rich and have no time to support one of the most stable and awesome OS out there, FreeBSD, you can try Minetest. It's a free and open-source clone of Minecraft.

I am sad that I paid and cannot play the game. I thought the whole point to java was to be cross-platform. Yet the devs didn't choose OpenJDK.
