Consider the following code :

   // This code safely publishes the Publishable object
   public static Publishable publishable= new Publishable();

I have seen such a way of publishing the custom Publishable object and I read that this is safe. My question is :

  1. Is this a really a way of safe publication ?
  2. If the answer to 1 is no then why ? If yes, then also please explain why ?

    According to JCiP:

    static initializers are executed by the JVM at class initialization time […] this mechanism is guaranteed to safely publish any objects initialized in this way.

    Reference: JLS 12.4.2 – item 9:

    Next, execute either the class variable initializers and static initializers of the class, or the field initializers of the interface, in textual order, as though they were a single block.
