> It is possible for a NullPointerException (NPE) to be thrown by the JakartaMultiPartRequest file upload processing.  It is a boundary condition, possible if struts.multipart.maxStringLength has not been set and the upload request also includes normal fields (in addition to the file).
>  
> Given defaults for configuration, it is unlikely to be encountered by most users/configuration.  A potential mitigation PR may follow.
