Oracle has announced that the end of life (EOL) of Java SE 6 has been set to February 2013. Which means that if you have not already upgraded to Java SE 7, now is the time. You can read more about the Oracle Java SE Support Roadmap here.
And for you folks that think that Java SE 7 is a new thing, well, I'm afraid that you are poorly updated. The Java SE 7 was released in February 2011.
