Hello there,

I came across the Chapter 02 example where we are compiling a single module from scratch. When I try to compile the example with the following command:

javac -d out --module-source-path src --module packt.addressbook

I see the following:

import sun.misc.Unsafe;
          ^
  (package sun.misc is declared in module jdk.unsupported, but module packt.addressbook does not read it)
1 error

I am using java 11 to run the examples, I am not sure if this is related and I was navigating the code and I saw that the import is not used in the code:

Anyways I was wondering if the import is needed in the code? Is it related to the java version I am running?
