> Oracle makes me too uneasy. Can I use Java without the worry of incurring Oracle's wrath?

Hey! I work at Microsoft and helped us launch the Microsoft Build of OpenJDK.

I can categorically say that yes you can use Java without worrying. As long as you don't use a commercial binary from a vendor that has certain licensing restrictions.

Our build of OpenJDK is free for any use, and comes with commercial support (you know, the one you can open a ticket and ask us to look into the issue) at no extra cost for workloads on Azure.
