What kind of preposterous assumption it is?(Sorry if I sound rude) Yes, few developers tend to come outside and explore but that doesn't mean that everyone is leaning towards Node. I am a Java guy, and I'm surrounded completely with Java crowd. I took interest in Node and started working on it for my hobby projects, and I went to gyan about Node during our usual discussion. The moment they hear JS, they simply ignore the topic. Yes, none of my colleagues are ready to listen about having JS in the backend. Forget about backend, making them agree to work with AngularJS was a battle for me, and I still see people do some silly mistakes in Angular, but that is because they are trying to do it in Java way!
So, As I said, maybe, just maybe, some are willing to look out of their window, but not many of them. I'm looking for a guy with whom I can talk about Nodejs and find no one in my company.
Is it? :) Jokes aside do you have any particular reason to say that's happening?
In my experience, Java devs will do almost anything to avoid using or learning another language... much like contemporary Javascript devs tend to do absolutely everything in Javascript.
Anecdotally the only Javascript thing I've seen Java devs really get excited about was Angular 1.
Actually most of the Java / Full Stack developers are working on some frontend frameworks already (Angular / React or atleast jQuery). So, when they see Node can execute the same code on server (not really :P) they move to try that out.
If you love JavaScript (Which most of developers do) you will definitely use node or at-least give it a try.

Do you have stats / data to backup your assumption ?
Majority of Java devs I know doesn't want to touch JS with a pitch fork, nevermind NodeJS.
