It would appear that Mule and Java 7 are incompatible on all platforms.  You will probably have to find a way to roll back to Java 6.

I don't know if I can go back.. Is this the end of MULE for me?

[Chuckie Chuck]

I am not sure of what the next step is yet.  I have to do some more research.  I did not have my MAC with me when I got your email, but I will take it home with me tonight and investigate.  My Lepard based MAC still works fine, but I have not tried my Lion based MAC, which I know is fully updated, so I expect I should be able to duplicate the issues.

Thanks for looking into it Chuckie, I appreciate it.


@the rest of planet mule community: no one else updated java? I can't be the only one with this problem. I see games going steadily like normal, I'm a little confused.

This is a common issue on Oracle's Java 7 on Mac OS X 10.7 and 10.8.
The simplest solution is to go back to using Apple's Java version 6. You can do it like this:

To uninstall the Java 7 internet plugin (Java 7 JRE):
Go to /Library/Internet Plug-Ins/ and delete the JavaAppletPlugin.plugin bundle.

To uninstall the Java 7 JVM bundle (Java 7 JDK):
Go to /System/Library/Java/JavaVirtualMachines/ and delete anything whose name starts with jdk1.7.0

Install a Java 6 runtime:
Open http://www.java.com/en/download/testjava.jsp
Your browser will show a security warning. Click the button to allow the Java applet to run.
You will be asked to install Java 6 for OS X from Apple.

Now you should be able to Play Planet Mule again

I deleted those files... but then it just asks you if you want to install java 7 again. Java 6 does not seem to be available. There is a archive page, but I dont see anything for mac there. The Mac Software Update automatcally goes to v7 too. 

[Chuckie Chuck]

Yeah, I got a warning on my mac that once Java 7 was installed, Apple Java would no longer be available, scared to let it update.

I uninstalled java and just tried to open mule and that did work (prompted me to install 6 from there).  Thanks Peter!. If anyone else has same issue, just delete the files and open mule. Going directly to Software Update will only give 7 as a choice I think.

Ok I guess I still can't actually join a tournament. I hope didn't muck something up deleting the files. I think I may have deleted the contents of the "HD/Library....JavaVirtualMachines" folder in addition to "SYSTEM/Library....JavaVirtualMachines" folder. I repeated the original steps after I did that but it didn't replace that folder with any files during reinstall.

Any ideas? I was able to play a training game just fine but could not 'join' tournament
