technical error on Java Language Spesification documentation

[Lestari N.S]

Dear oracle,

I read the documentation of java 8, which I downloaded the pdf from java
official website. I've ran one example program on sub-chapter "1.2 Example
Programs", and it was not producing the output "Hello, world" as mentioned
on the e-book. I just want to do my best as a reader to give feedback for
improvement purpose. Thank you.


Sincerely,
Lestari Ningratna Sari
