Java泛型是否允许在诸如short之类的原语数组中节省内存？(Do Java generics allow for memory savings in arrays of primitives such as short?)

 我做了一些谷歌搜索，但我一直无法找到这个问题的决定性答案。 为了澄清，请考虑这样的类： 
 
public class MyContainer<T> {
    private T[] _store;
    private int _size;
    ...
}
 
 是否有可能通过使用short和int类型的数组来实现内存节省，尽管事实上必须使用Short和Integer等原始包装类声明带有MyContainer引用的变量，并且MyContainer实例必须用这些相同的包装类创建？ 
 
 在我的搜索中，我发现Java编译器将类型擦除应用于泛型，但我不太确定我现在可以假设Java没有对通用类型数组进行某种优化。 
 
 有没有人有证据支持或反对这个？ 提前致谢。 

I've done a bit of Googling, but I've been unable to find a decisive answer to this question. For clarification, consider a class like this:
 
public class MyContainer<T> {
    private T[] _store;
    private int _size;
    ...
}
 
Is it possible to achieve the memory savings one would get by using an array of type short vs. int, despite the fact that a variable with a reference to MyContainer must be declared with primitive wrapper classes like Short and Integer, and instances of MyContainer must be created with those same wrapper classes?
 
In my searches I found that the Java compiler applies type erasure to generics, but I'm not so sure that I can now assume Java does not have some sort of optimization for generically-typed arrays.
 
Does anyone have evidence for or against this? Thanks in advance.
