Introducing the String class in re-export sample is bit artificial and decreases readability. At least it should be renamed to something like LibraryString.
There suddenly appears the Query library in the text not being introduced anywhere. Don't get confused. The only important thing to know about this library is that it is returning the re-exported String on computeReply() method call.
The text is unfortunately silently referring to the side note story (code completion). So when you read the text first and the NetBeans stories later you can get confused slightly.
"Because they are protected, calling them from a subclass has no meaning, as they don’t provide any implementation in the defining class." should be "Because they are abstract, calling them from a subclass has no meaning, as they don’t provide any implementation in the defining class."

Type parameter is bit confusing. While most of the people are familiar with single uppercase letter (like T, E, V) and can easily recognize them as a type parameter author is using Configuration and switch to C just a few lines later.
