Questions about whether the class load thread and the main thread are a threads

See in-depth understanding of the Java Virtual Machine (second edition), the author of the 226 page gives a piece of code, explaining the class loader blocking problem, feel this code and the results given in the book is biased, self-validation, and the code in the book run inconsistent results.

    Static{        if(true) {System.out.println (Thread.CurrentThread ()+ "Init Deadloop");  while(true){            }        }    }     Public Static voidMain (string[] args) {//<------thread will not execute hereRunnable r =NewRunnable () { Public voidrun () {System.out.println (Thread.CurrentThread ()+ "Start"); NewCinitdeadloopclass (); System.out.println (Thread.CurrentThread ()+ "End");        }        }; NewThread (R). Start (); NewThread (R). Start (); }        //output only Thread[main,5,main] init deadloop
