Why my class is not getting loaded

Question

I am confused with the output of the below code. I know first static block gets executed after class loading but why is my class Test6 not getting loaded. Can someone please clarify.

package com.vikash.General;

public class Test5 {

    public static void main(String[] args) {
        System.out.println(Test6.FOO);
    }
    static {
        System.out.println("Initializing B");
    }
}
class Test6{

    public static final String FOO = "foo";
    static {
        System.out.println("Initializing A");
    }
}

Answer 1

Test6.FOO refers to Test6, but the field is a public static final String initialized from a compile-time constant, so it will be inlined by the compiler, and Test6 does not need to be loaded at all.

Answer 2

It seems to be because the compiler is inlining the reference to the string literal "foo", so the JRE doesn't actually bother loading Test6 to get it.

If you make a change such as:

public static final String FOO = new String("foo");

then the class Test6 does get loaded (and its static block gets executed).
