Curious logic you have. "It doesn't have a constant stream of fixes. That proves it's no good. Things that need fixing are better than things that don't need fixing".
Also, it hasn't been Open Source in several years. That makes Solaris utterly irrelevant in my world. This blog post is suggesting Linux users move to Solaris. It's just a bizarre recommendation, made as an off-the-cuff assertion with no reasons given.
Also, Oracle. What hacker chooses to be beholden to Oracle?
How about almost every single Java, Scale, Clojure etc developer. We are all using Oracle's JVM and they have been unquestionably a fantastic steward of the Java platform. I know the company deserves a lot of criticism but remember it is a big company with many different departments.
That is debatable. First off, we're not all using Oracle's JVM :) It's also not at all clear that Oracle has been "a fantastic steward of the Java platform." They don't appear to have totally wrecked it, but that's a low bar for "fantastic."
