Summary: java.lang.ArrayIndexOutOfBoundsException Bug Report
Key: PDFBOX-5737
URL: https://issues.apache.org/jira/browse/PDFBOX-5737
Project: PDFBox
Issue Type: Bug
Affects Versions: 3.0.0 PDFBox
Reporter: Xiaohan Zhang
Attachments: crash-38ee70b5cb74519b642c150694f601239f492168
Recently we discovered a bug in latest pdfbox (3.0.0).
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.
