[jira] [Comment Edited] (PDFBOX-3677) NullPointerException in
Type1Parser.read
[ https://issues.apache.org/jira/browse/PDFBOX-3677?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15856351#comment-15856351 ]

[~guebeli] please try with a snapshot:
https://repository.apache.org/content/groups/snapshots/org/apache/pdfbox/pdfbox-app/2.0.5-SNAPSHOT/
The change will avoid the NPE but the file will still bring trouble. You could extract the (type 1) font with the PDFDebugger command line application. Just go to the resources, the font, then click on each font until it fails. Then search that part of the tree for "FontDescriptor" and then "FontFile", there's the font file. Right-click to save. I suspect that the file is too short.
Please give feedback what happens now.

> Project: PDFBox
> Issue Type: Bug
> Components: FontBox
> Affects Versions: 2.0.3, 2.0.4
> Environment: Windows 10, java version "1.8.0_25"

> Text extraction from certain PDFs is not possible and PDF Box responses with NullPointerException. Text extraction from same PDF with version 1.8.13 is working.
> Originally the issue was discovered while using the newest Apache Tika 1.14 library. I can not down-grade to PDF Box 1.8.13 with Apache Tika 1.14.
> Unfortunately I can not provide the PDFs that fail to you. However, I did some testing and found out that “Token token = lexer.nextToken();” return Null.

> java.io.IOException: Found token=null but expected NAME
