[jira] [Commented] (TIKA-1742) StackOverflowError parsing a PDF
with ExtractInlineImages=true
[ https://issues.apache.org/jira/browse/TIKA-1742?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14904360#comment-14904360 ]
Tim Allison commented on TIKA-1742:
-----------------------------------
The HORROR! If it were a second rate conference, it would be one thing... (not sarcasm, I'm an nlp'er).
I confirmed that this same bug happens in pure PDFBox 1.8.11-SNAPSHOT's ExtractImages. I opened PDFBOX-2988.
