Review Comment:
> I think the problem of this code is quite obvious. Once there is a null value, an exception will be thrown. I think it can be avoided in advance, and the code will become streamlined after modification.
If we can guarantee the value don't have `null`, why do we need to filter them?

Will the bug never happen? If so, the pr isn't necessary.

> Yes, at present, I have no way to understand the meaning of handling null in the original sorting. So for the sake of insurance, I added filtering conditions.
So this pr should be an improvement, not a bugfix?

Where do you introduce the `null` value? I can't find it in this case.

Review Comment:
```
sizeList.add(null);
sizeList.sort((entry1, entry2) -> {
if (entry1 == null && entry2 == null) {
return 0;
}
if (entry1 == null) {
return -1;
}
if (entry2 == null) {
return 1;
}
if (entry1.getValue().get() > entry2.getValue().get()) {
return 1;
} else if (entry1.getValue().get() == entry2.getValue().get()) {
return 0;
}
return -1;
});
```
I added like this, in this way, the sub sorting causes null to be placed in front of `sizeList`, and null pointer will be thrown during traversal. Another point is that I'm not sure about the reason for sorting null here. I think `remoteStotoragePathCounter. entrySet()` should not contain null values.

Review Comment:
Yes, at present, I have no way to understand the meaning of handling null in the original sorting. So for the sake of insurance, I added filtering conditions.

Review Comment:
I think the problem of this code is quite obvious. Once there is a null value, an exception will be thrown. I think it can be avoided in advance, and the code will become streamlined after modification.

Review Comment:
Yes, because there is no better way to introduce a null value. This happens when I manually add a null value to the `sizeList` in the `pickRemoteStorage` method. Because this test is similar to `refreshTest`, I think one method and one test will be better. WDYT?

Do the case cover your situation? Could we put the case into refreshTest?

Review Comment:
Where do you introduce the `null` value? I can't find it in this case. What do you mean about `one method and one test`?
