I read it less as "Java is tiny" and more as "Java developers can be peculiarly insular and conservative, by the standards of other communities."
Considering that as recently as 4 years ago I was working on a project where we still had a hard requirement to support running in Java 7, and this kind of thing was not considered unusual, I can't really disagree too strongly with that. Yes, that was still inside of Java 7's extended support period, so there was really nothing unusual or surprising about this, from a Java developer perspective. But that's kind of the point.
It's also not really a bad thing, considering what kinds of things run on Java. Mainframe developers have a similar thing going on, for a similar and similarly good reason.
