Java just has an incredibly long, deep, relationship with the open source/FOSS world that is going to take C# a lot of time to catch up with. Java's also consistently had a much better story with backwards/forwards compatibility and versioning. I haven't used it in years, but I didn't find the anywhere near as full an ecosystem around C#, it's tooling, it's libraries, etc. It didn't help that there was a lot of confusion around what ran on which runtimes/versions. Perhaps it's changed since then.
