I am testing the robustness of POI using fuzzing with massive auto-generated
inputs.

Developers who are integrating POI into their program, may not be aware of the
uncaught exceptions. As a result, the stability of the program is compromised.

If this POI API only expects certain file format, it is better to implement
some validation checks instead of accepting all file types to avoid the
uncaught exceptions.  

Note: in the original description, I missed out some content for the impact of
the vulnerability and I had added it in the comment section. 
Sorry for the inconvenience caused!
