Like many people, I'm eagerly awaiting the final release of Solaris 10.
Today's reason isn't based on some of the fantastic new features - like zones and dtrace - but on something rather mundane.
Solaris 10 comes with jdk 1.5 (or 5.0 or whatever number they dreamt up this week - you know what I mean though).
I've been upgrading some of our web servers (and building new ones for deployment) using tomcat 5.5.4. Which wants jdk 1.5. (It doesn't require it, but it's quite keen.) I don't see a problem with this, but it's meant I've had to drop a copy of jdk 1.5 (actually, update 1 which just came out) on the machines. And that will be one less chore I need to worry about once Solaris 10 actually hits the streets.
