> When I performed IO operations using the IOUtils toolkit provided by cxf, a
> null pointer exception occurred. Therefore, I read IOUtils code. And I found
> that some pubilic methods in this class missed parameter verification which
> could be result of Null pointer exceptions.
> For example,

> when the input was null,the code would throw an excetion when excuting
> input.available().
> The same problem occurred with the methods copyAtLeast, loadIntoBAIS,
> transferTo, etc.
