No, but I think it's a big contributor to the network effect advantage Java has.

I'm not bashing the language - it certainly has its defenders. Some people regard simplicity as a virtue (although I'd question how simple Java is nowadays). But I think even ardent Java fans will concede, Java has some deficiencies as a language. The main reason people use Java, is that people know Java. And the main reason they know Java, is because it is used.

It takes a long time to kill a network effect.
