> Key: PDFBOX-5833
> URL: https://issues.apache.org/jira/browse/PDFBOX-5833
> Project: PDFBox
> Issue Type: Bug
> Components: Utilities
> Affects Versions: 3.0.2 PDFBox
> Environment: Happens both on our server environment (Linux) and when
> testing locally (Windows)
> Reporter: Lucas Welscher
> Priority: Major
> Labels: bug, regression
> Fix For: 3.0.3 PDFBox
>
> Attachments: Infun2324.L02.Control.Structures.pdf

>
> After upgrading from PDFBox 3.0.1 to version 3.0.2 I experienced a
> NullPointerException when using the split() method:
> {code:java}
> java.lang.NullPointerException: Cannot invoke
> "org.apache.pdfbox.pdmodel.common.PDNumberTreeNode.getNumbers()" because
> "tree" is null
> at
> org.apache.pdfbox.multipdf.PDFMergerUtility.getNumberTreeAsMap(PDFMergerUtility.java:1156)
> at org.apache.pdfbox.multipdf.Splitter.cloneStructureTree(Splitter.java:192)
> at org.apache.pdfbox.multipdf.Splitter.split(Splitter.java:135)
> {code}
>
> When testing with different inputs, I noticed that the issue only occurred
> when using a PDF generated from Keynote. I attached an example below to
> reproduce the issue.
> Downgrading to 3.0.1 again solves the issue.
> This is proably caused by PDFBOX-2725 and
> [this|https://svn.apache.org/viewvc?view=revision&revision=1915447] commit.
> The issue happens in this segment of Splitter.java:
> {code:java}
> PDNumberTreeNode srcParentTree = srcStructureTreeRoot.getParentTree();
> // srcParentTree is null here
> Map<Integer, COSObjectable> srcNumberTreeAsMap =
> PDFMergerUtility.getNumberTreeAsMap(srcParentTree);
> {code}
>
