             Summary: `NullPointerException` when intersecting area with null clipping path
                 Key: PDFBOX-5313
                 URL: https://issues.apache.org/jira/browse/PDFBOX-5313
             Project: PDFBox
          Issue Type: Bug
          Components: Rendering
    Affects Versions: 2.0.24
            Reporter: Henry Iguaro


Hey guys!

We got a PDF that manages to trigger the following NPE from {{PageDrawer}}:
 java.lang.NullPointerException: null
	at java.desktop/java.awt.geom.Area.<init>(Area.java:126)
	at org.apache.pdfbox.rendering.PageDrawer.fillPath(PageDrawer.java:900)
	at org.apache.pdfbox.contentstream.operator.graphics.FillNonZeroRule.process(FillNonZeroRule.java:37)
	at org.apache.pdfbox.contentstream.PDFStreamEngine.processOperator(PDFStreamEngine.java:933)

The file even breaks on {{pdf-debugger}} (it fails to render).
 
*Unfortunately, I can’t share the file.*

Looking at the documentation for [{{Graphics.getClip()}}|https://docs.oracle.com/javase/6/docs/api/java/awt/Graphics.html#getClip()], it mentions that the result can be {{null}}, and if {{null}} is passed to the {{Area}} constructor this ends up in a {{NullPointerException}}. Further studying the {{PageDrawer}} code, it seems that {{graphics.getClip()}} shouldn't return {{null}}, however, we proposed a small fix in the following PR that seems to do the trick:
