You haven't migrated to Java 7 yet? Well, it looks like you will have a bigger incentive soon. Java 6 will have its last public release on the 19 February 2013. After that, you'll need to pay to get the security fixes and bugfixes. That's what you get with Oracle.
In the old days, when Sun shone on Java, all updates were public. Alas, money is the keyword now.
But in anything, there is something good. Java 7 is the latest and greatest Java, and it's been out for more than a year. It's time to move forward.
