If you're running Snow or Snow Leopard, Apple pushed out Java updates that you might want to grab. The upgrade includes several security fixes.
A Macworld story begins, "If you thought you just heard a disturbance in the Force -as if millions of voices cried out in terror and were suddenly silenced - then take a deep breath and relax: it's just a pair of Java software updates for Mac OS X," writes Dan Moren.
The Java for Mac OS X updates came out on Thursday and are available on Apple's Support downloads page and via System Update. These updates disable J2SE 1.4.2.
