------------------------------------------
Summary: ClassCastException in getOptionalContentGroups
Key: PDFBOX-3942
URL: https://issues.apache.org/jira/browse/PDFBOX-3942
Project: PDFBox
Issue Type: Bug
Components: PDModel
Affects Versions: 2.0.6
Reporter: Vlad-Tudor Marchis
Priority: Minor
Attachments: PDOptionalContentProperties.java
I noticed this issue when trying to remove a set of layers I previously added
on a multi-page PDF. I noticed it in version 2.0.6, but might be present in
others.
Here is a stacktrace snippet:
Caused by: java.lang.ClassCastException: org.apache.pdfbox.cos.COSDictionary
cannot be cast to org.apache.pdfbox.cos.COSObject
at
org.apache.pdfbox.pdmodel.graphics.optionalcontent.PDOptionalContentProperties.getOptionalContentGroups(PDOptionalContentProperties.java:180).
I looked at the source and saw the toDictionary method that seemed to be used
in every other place so I just put in in place and it seems to have solved the
issue.
I've uploaded the updated file, the one that I'm using, which you can review
and include in your project if it's a valid fix.
