Key: PDFBOX-5339
URL: https://issues.apache.org/jira/browse/PDFBOX-5339
Project: PDFBox

Reporter: Huang Wenjie
Recently we (Zhang Cen and Huang Wenjie) found and submitted several bugs of latest pdfbox (3.0.0-alpha2).
For your convenience, here lists the bug summary for all reported bugs (will keep it updated).
Note that each issue is a unique bug (we sorted and refined them from thousands of crashes)
Any discussion about the bugs are welcome.
## Unqiue Bugs Found
<p style='text-align: justify;'>Recently we ([Zhang Cen](https://github.com/occia) and [Huang Wenjie](https://github.com/ZanderHuang)) discovered a series of bugs in latest pdfbox (3.0.0-alpha2).
Every bug we reported in the following is unique and reproducable. Furthermore, they have been manually analyzed and triaged in removing the duplicates.
<br />Due to the lack of contextual knowledge in the pdfbox library, we cannot thoroughly fix some bugs hence we look forward to any proposed plan from the developers in fixing these bugs.</p>
