RedHat? I don't. Had that happened, Java, ZFS, MySQL, VirtualBox, etc would now likely all be required components of systemd. (Yes, I'm being a little facetious, but I really believe RedHat has some sinister ulterier motives. They've been absolutely horrible with systemd, Gnome, GTK3, etc.)
What happened to Sun was an outright catastrophe, but we've mostly recovered with OpenZFS, MariaDB, Jenkins, LibreOffice, etc. The major piece we're missing is a clean fork of VirtualBox. Android's also not in a good state to replace desktop Java, but it could conceivably be one day at least.
To be fair, I use VB every day and it is getting frequent updates and hasn't crashed in 2 years, it used to crash quite often when Sun developed it. Maybe it could be something better, or amazing and different, but it's still free and very stable, so I'm quite happy.
