Sun doesn't care about my preferences
J2SE and J2EE are known brands and I believe there are some copyright issues related to it
Well, enough complaints for such small stuff... I've to keep some for Apple when they release Mac OS XI!
Update: Apparently, I'm not the only one who is confused, David Flanagan is also wondering about the version numbers.
