That's a rationalization, if I ever saw one.

Java has tons of documentation online, detailed API references, tutorials, etc. If there are many Java books, that's because of the demand for them and the language, not of some "mystic" BS quality the language has that needs more books.

For the same reason there are tons of Java jobs, many more than, say, Ruby jobs. It's not because "Java is more difficult and needs more programmers for the same task".
