------------------------------
Summary: Some public methds in org.apache.cxf.helpers.IOUtils
lacks parameter verification, which may cause Null pointer exceptions
Key: CXF-8610
URL: https://issues.apache.org/jira/browse/CXF-8610
Project: CXF
Issue Type: Improvement
Components: Core
Reporter: panda2021
Attachments: image-2021-10-25-11-53-27-620.png
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,
!image-2021-10-25-11-53-27-620.png!
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.
