John Petersam created PDFBOX-5453: ------------------------------------- Summary: ClassCastException (PDColor.java:66) Key: PDFBOX-5453 URL: https://issues.apache.org/jira/browse/PDFBOX-5453 Project: PDFBox Issue Type: Bug Components: PDModel Affects Versions: 2.0.26, 2.0.24 Reporter: John Petersam
We are currently running PDFBox 2.0.24 & 2.0.26, but I see the code is identical in the trunk. Certain PDFs are throwing the exception shown below in our production system. In these cases, rather than the array containing a list of COSNumbers, it actually contains a single item - another COSArray. That COSArray then has an array of COSNumbers. If I insert the following lines of code at line 62 to use the inner COSArray, the PDF renders properly. {{ *if ((array.size() == 1) && (array.get(0) instanceof COSArray))*}} {{ *array = (COSArray) array.get(0);*}} Unfortunately, we do not generate the PDFs ourselves and our documents contain sensitive information so I am unable to provide an example. *Exception:* {{java.lang.ClassCastException: class org.apache.pdfbox.cos.COSArray cannot be cast to class org.apache.pdfbox.cos.COSNumber (org.apache.pdfbox.cos.COSArray and org.apache.pdfbox.cos.COSNumber are in unnamed module of loader 'app')}} {{at org.apache.pdfbox.pdmodel.graphics.color.PDColor.(PDColor.java:66)}} {{at org.apache.pdfbox.pdmodel.interactive.annotation.handlers.PDFreeTextAppearanceHandler.extractNonStrokingColor(PDFreeTextAppearanceHandler.java:424)}} {{at org.apache.pdfbox.pdmodel.interactive.annotation.handlers.PDFreeTextAppearanceHandler.generateNormalAppearance(PDFreeTextAppearanceHandler.java:111)}} {{at org.apache.pdfbox.pdmodel.interactive.annotation.handlers.PDFreeTextAppearanceHandler.generateAppearanceStreams(PDFreeTextAppearanceHandler.java:75)}} {{at org.apache.pdfbox.pdmodel.interactive.annotation.PDAnnotationMarkup.constructAppearances(PDAnnotationMarkup.java:897)}} {{at org.apache.pdfbox.rendering.PageDrawer.showAnnotation(PageDrawer.java:1521)}} {{at org.apache.pdfbox.rendering.PageDrawer.drawPage(PageDrawer.java:281)}} {{at org.apache.pdfbox.rendering.PDFRenderer.renderImage(PDFRenderer.java:347)}} {{at org.apache.pdfbox.rendering.PDFRenderer.renderImage(PDFRenderer.java:268)}} -- This message was sent by Atlassian Jira (v8.20.7#820007) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@pdfbox.apache.org For additional commands, e-mail: dev-h...@pdfbox.apache.org
