Here is the solution to fix the app. This should work with versions 3.5.2. or 3.5.3
sudo ln -s /Library/Java/JavaVirtualMachines/jdk1.7.0_17.jdk /System/Library/Java/JavaVirtualMachines/1.6.0.jdk[/php]
You may need to change jdk1.7.0xxxx to the correct version that is installed on your system.
Also, I was informed that Crashplan is working on a native version of the client for OS X. I can’t wait to try it out.
