这个功能没错，类的finale变量(static final 修饰)确实可以实现延迟初始化， 看成实例变量只有finale修饰了。
不过，不知道英文官网为什么 不想描述这一功能点了。

无论是不是静态，理应都是延迟初始化的。

是的，这句话应该被删掉，应该是文档同步的时候上游做了修改但是中文没有及时改动，我马上发一个 PR 来解决这个问题。

从我的这个case中， '---initA---'是先于"will use aa"打印的，如果加上static修饰 才是"will use aa"先打印

因为没有经过 static 修饰的 aa 是 VariableClass 的成员变量。final 修饰的成员变量是在构造时一同初始化的。顶层（或者说全局） final 变量和 static final 都是延迟初始化的。

移除译文的说明后已经没有误导信息了，如果要修改那么去掉 "类的 final 变量" 也符合条件。
