I'm not the expert (that would be Craig or someone else with his level of knowledge and experience...Craig wrote the document), but I think you are confusing the Bootstrap ClassLoader with bootstrap.jar.
"Bootstrap - This class loader contains the basic runtime classes provided by the Java Virtual Machine, plus any classes from JAR files present in the System Extensions directory ($JAVA_HOME/jre/lib/ext)." I think that means that bootstrap.jar has the Bootstrap ClassLoader in it, and that class loader loads the basic runtime classes provided by the JVM, which, in this case, would be the classes in rt.jar. I don't think it means that bootstrap.jar supersedes or replaces rt.jar. I'm really hazy on the whole concept of a "class loader" though, so take whatever I say on the subject with a BIG grain of salt until someone else can chime in and correct me if I'm wrong.
