Where is my Java console on OS X? I can't find the Java console in Preferences nor in Utilities. 
Can I open the Java console from a Terminal command?

Running OS X 10.7.5 and Java version 1.6.0_65
It is somewhat maddening, but the Java console won't display unless a Java application is actually running. The easiest way to get it started is to visit https://www.java.com/verify/ from the Firefox browser.
