### Environment
branch: master

functions take & put in org.apache.dubbo.common.utils.Stack consider no the situation that index plus mSize is negative .
```java
public E get(int index) {
        if (index >= mSize) {
            throw new IndexOutOfBoundsException("Index: " + index + ", Size: " + mSize);
        }

        return index < 0 ? mElements.get(index + mSize) : mElements.get(index);
    }

public E set(int index, E value) {
        if (index >= mSize) {
            throw new IndexOutOfBoundsException("Index: " + index + ", Size: " + mSize);
        }

        return mElements.set(index < 0 ? index + mSize : index, value);
    }

public E remove(int index) {
        if (index >= mSize) {
            throw new IndexOutOfBoundsException("Index: " + index + ", Size: " + mSize);
        }

        E ret = mElements.remove(index < 0 ? index + mSize : index);
        mSize--;
        return ret;
    }
```
the implementations are not strict.
private int mSize = 0;
    private List<E> mElements = new ArrayList<E>();
    public Stack() {
    }
    /**
     * push.
     *
     * @param ele
     */
    public void push(E ele) {
        if (mElements.size() > mSize) {
            mElements.set(mSize, ele);
