问题
I'm used to using Console.app to see System.err/out.println() output from my compiled Java applications. I just installed a Java application on a new 10.8 machine, and now Console.app is mute.
How do I enable Java output in Console.app on 10.8?
I'm fiddling with Java Preferences, which I downloaded from this link (found on this thread), but nothing seems to do the trick.
