1. Unique Bugs Found

Recently we (Zhang Cen, Huang Wenjie and Zhang Xiaohan) discovered a series of bugs in latest metadta-extractor (2.16.0).
Every bug we reported in the following is unique and reproducable. We sorted and refined them from thousands of crashes.
Furthermore, they have been manually analyzed and triaged in removing the duplicates.

Due to the lack of contextual knowledge in the metadta-extractor library, we cannot thoroughly fix some bugs hence we look forward to any proposed plan from the developers in fixing these bugs.
