[jira] [Commented] (PDFBOX-1125) NullPointerException when saving
Document
[ https://issues.apache.org/jira/browse/PDFBOX-1125?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13141100#comment-13141100 ]
Gerhard Temper commented on PDFBOX-1125:
----------------------------------------
I have the same problem with pdfbox version 1.6 - using pdfbox version 1.4 the problem is not reproducible:
An additional check before calling doWriteSignature in the visitFromDocument function (COSWriter.java) fixed the problem:
--- COSWriter.java.ori 2011-06-28 21:35:28.000000000 +0200
+++ COSWriter.java 2011-10-31 12:05:20.763036700 +0100
@@ -1036,7 +1036,8 @@
else
doWriteXRef(doc);
doWriteTrailer(doc);
- doWriteSignature(doc);
+ if(incrementalUpdate)
+ doWriteSignature(doc);
return null;
