Huzzah! Java 6 has been approved by the JCP. The final results on JSR 270 show that the voting was 13 for, none opposed, with three not voting. As I understand it, this is the final step toward officially releasing Java 6 to the masses.
Honestly, give Java 6 a shot. I've been using it constantly because of the performance gains, and JRuby support for 223 is already available. This is the first Java release during my time at Sun, and I'm extremely proud to be a part of this team.
