hashmap中的clone为什么是shallow copy of this map

Question

public Object clone() {
HashMap result = null;
try {
result = (HashMap)super.clone();
} catch (CloneNotSupportedException e) {
// assert false;
}
result.table = new Entry[table.length];
result.entrySet = null;
result.modCount = 0;
result.size = 0;
result.init();
result.putAllForCreate(this);

    return result;
}

新建Entry，把原来Entry中数据放到新的Entry中。新的HashMap与旧的HashMap操作没有关系了，为什么还是shallow？

Answer 1

javadoc上说得很清楚呀
