Minecraft (and probably some other applications) won't run on a System with the preinstalled Java removed and the current JDK 7 installed. I already symlinked the Java 6 directory to the current one. Other applications like Adobe Illustrator that need Java work with this fix. The error message states no compatible version of java 1.5+ is available.

Screenshot of the error message

What is a reasonable explanation why that application runs on Java 7 on Linux and Windows but not on Mac, and what can be done for it to do so?

Output of /usr/libexec/java_home -V:

Matching Java Virtual Machines (4):
    1.7.0_17, x86_64:   "Java SE 7" /Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
    1.7.0_17, x86_64:   "Java SE 7" /Library/Java/JavaVirtualMachines/jdk1.7.0_17.jdk/Contents/Home
    1.7.0_17, x86_64:   "Java SE 7" /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
    1.7.0_17, x86_64:   "Java SE 7" /System/Library/Java/JavaVirtualMachines/jdk1.7.0_17.jdk/Contents/Home

/System/Library/Java/JavaVirtualMachines is a Symlink to the /Library/ one, and 1.6.0.jdk is a symlink to jdk1.7.0_17.jdk, terefore only one JDK is being installed.

    Yes, I have seen this topics. The second one does adress another issue, which I have adressed before ("I already symlinked the Java 6 directory to the current one"). The first one basically only says to reinstall Java 6. – Appleshell Apr 8 '13 at 3:24
  • What is your current JRE version? – James Graham Apr 9 '13 at 21:08
  • @JamesGraham java -version java version "1.7.0_17" Java(TM) SE Runtime Environment (build 1.7.0_17-b02) Java HotSpot(TM) 64-Bit Server VM (build 23.7-b01, mixed mode) – Appleshell Apr 9 '13 at 21:15

    @AdamS the issue is that Java 7 uses a different Info.plist to Java 6 and so needs to be edited - report as a bug to Minecraft - for details see these answers on SO and AskDifferent -for an app to produce the correct bundle - and there is another great answer on AskDifferent I can't find now – user151019 Apr 13 '13 at 19:33

Minecraft for the Mac and other Java applications are routinely packed with Apple's JavaApplicationStub. JavaApplicationStub is a small program that decodes the Info.plist inside the application, detects Apple Java (6), shows the "To open this application you need to install the legacy Java SE 6 runtime" error message (if Apple Java isn't installed) and finally invokes Apple Java with the correct arguments to make the app go. The trouble is that JavaApplicationStub is hardwired with Apple Java detection and loading. JavaApplicationStub will almost never invoke Oracle Java, no matter what arguments you feed it or how you try to trick it into invoking Oracle Java.

The first step is to modify the Info.plist file in Minecraft to take JavaApplicationStub out of the loop and replace it with something that is Oracle Java friendly. universalJavaApplicationStub is a bash script that auto detects Oracle Java or Apple Java and invokes the app. I've described the process in a blog post to make Minecraft for Mac work no matter what Java is installed:

http://svexpertise.blogspot.com/2015/08/make-mac-minecraft-work-on-oracle-java.html

Pretty much all solutions cope with JavaApplicationStub. Some involve satisfying it (by installing Apple Java), some involve avoiding it (by invoking the .jar directly) and some involve replacing it (by installing a custom bash script or universalJavaApplicationStub).

What is the terminal output stating the error?

Looking at this discussion:

http://www.linuxquestions.org/questions/linux-games-33/minecraft-not-running-on-java-7-a-929983/

The error output indicates that the Minecraft Java binaries are linked against 32bit versions. Looks like you have 64bit installed. Does your Java7 installation support 32bit?

Also, are you running the latest Minecraft code/mod updates/etc?

Edit:

Given the error message in the answer, it lead me to this:

2 things are needed to be changed to make it run on OSX x64 and this is what i done.. 

1) add in x86_64 to the Info.plist as follows: 
JVMArchs 

i386 
x86_64 
ppc 

2) Set the execute flag on the JavaApplicationStub file 
chmod +x /Applications/Minecraft.app/Contents/MacOS/JavaApplicationStub 

now it works :)

That was found at:

Via:

http://www.minecraftforum.net/topic/487766-fixed-lsopenurlswithrole-failed-with-error-10810/

Regarding checking java version:

$ java -version
java version "1.6.0_43"
Java(TM) SE Runtime Environment (build 1.6.0_43-b01-447-11M4203)
Java HotSpot(TM) 64-Bit Server VM (build 20.14-b01-447, mixed mode)

Indicates 64bit server VM in mixed mode. When testing with '-d32' and 'd64', the java runtime should report back with a help screen vs erroring out, though this doesn't rule out 32bit/64bit libraries in the paths that are missing.

java -d32

java -d64

But the chmod above might help more.

Note, I don't use Minecraft.app to start up MineCraft when I run it on a Mac. I do the following:

My wrapper script:

#!/usr/bin/env bash
java -Xmx3048M -Xms2024M -cp "$1" net.minecraft.LauncherFrame

And I run it by:

./run-minecraft minecraft.jar

I have the parameter because sometimes, I like running 3rd party wrappers around the MineCraft application itself.

AddOn:

Btw, this is the alternate method I use to fire up MineCraft, since MineCraft.app on the Mac has never worked reliably for me.

  • http://minecraft.net/download
  • Download the JAR file for "Minecraft for Linux / Other"

  • Test firing up with:

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

  • The terminal output is LSOpenURLsWithRole() failed with error -10810 for the file /Applications/Minecraft.app.. Minecraft.app is the latest from the website. How do I find out if my Java installation supports 32 bit? – Appleshell Apr 9 '13 at 22:08

    This is the Info.plist of the .app: pastebin.com/baea0VKX . How resp. where can I add x86_64 there? On another note: I could start the game with Minecraft.app/Contents/Resources/java/MinecraftLauncher.jar perfectly, so it definitely has something to do with the .app. – Appleshell Apr 11 '13 at 7:22

    I added the config block to your pastbin Info.plist file and re-pasted here: pastebin.com/EVRAvZtv Hope that works. – Wing Tang Wong Apr 11 '13 at 17:21

    Unfortunately it didn't work. I played around with the settings and also other things mentioned here (developer.apple.com/library/mac/#documentation/Java/Reference/…) but it didn't help either. When I tried to remove JVMVersions, it opened, but crashed immediately with the following error message: pastebin.com/CnFHxsBg – Appleshell Apr 11 '13 at 19:54

    Like I said, the .jar inside the .app works, and so does the .jar from the website. I was eager to get behind the reason that the .app does not work because the issue is not limited to the Minecraft.app but also Java Preferences.app (I assume to all .app wrapped .jar files.) But it seems that this is something that is not solvable so easily... I'll reward you with the bounty for your effort nevertheless and try to look into this again when I have more time. Thank you so far! – Appleshell Apr 11 '13 at 22:15
