Being payed as a Java developer, I'd like to point to some circumstances beyond the language, which is embedded in some kind of ecosphere in real life. In my case this consists of Maven and Spring. There are others, but these might be representative.

In such a world, dependency and complexity are separated into these two. Solving a specific task may end up in finding a suitable maven artifact for that task and then configuring it within Spring. I may end up with maybe some tens of lines consisting of Java code and configuration after a few days of work. (I'm sometimes joking about my own performance being measured in "lines per week", which may be less than 10.) The Java skills required for this kind of job are minimal. Handling Maven and Spring are the real challenges.
