Why are most graph databases written in Java?

Question

Database

Faced with the fact that most graph databases are written in Java. What is it connected with?

I don’t know what is the cause and what is the consequence, but I can say that in Java there is this: https://github.com/tinkerpop , but in dotnet I don’t remember this.
Actually, what will you get when you find out why graph databases are written in Java? Will it get any easier for you? Or is the real question still elsewhere?
