Re: This article conflates two important issues
"As we're all programmers here we all know that "lines of code" is a very misleading metric. I would like to see exactly what was copied; from what it sounds like its a set of interface classes which is (I suppose) how you'd specify an API in a language like Java."
Names of packages, names of classes, names of methods. Yes, only the declarations of a part of the API, of Java core libraries.
