[jira] [Commented] (PDFBOX-1234) NPE at
org.apache.pdfbox.pdmodel.interactive.form.PDAppearance.calculateFontSize(PDAppearance.java:551)
[ https://issues.apache.org/jira/browse/PDFBOX-1234?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14304505#comment-14304505 ]
Christer Palm commented on PDFBOX-1234:
---------------------------------------
Yes the PDF is of course an example of one of those widely circulated invalid PDF:s that are still rendered/repaired by Adobe Reader. I'm sorry if that wasn't clear from the beginning.
I don't know what the PDFBOX policy is on invalid PDF:s, but as a minimum I'd expect it to throw a meaningful exception, not a NPE.

> Key: PDFBOX-1234
> URL: https://issues.apache.org/jira/browse/PDFBOX-1234
> Project: PDFBox
> Issue Type: Bug
> Components: AcroForm
> Affects Versions: 1.8.4, 2.0.0
> Reporter: Christer Palm
> Assignee: Maruan Sahyoun
> Fix For: 2.0.0
>
> Attachments: 200221.pdf, SetPDFFieldValueTest.java, fw8bene--dft.pdf
>
>
> Using SVN trunk revision 1291094 (2012-02-18)
> Getting the following stack trace when trying to call PDField.setValue() on a AcroForm field in the attached document;
> java.lang.NullPointerException
> at org.apache.pdfbox.pdmodel.interactive.form.PDAppearance.calculateFontSize(PDAppearance.java:551)
> at org.apache.pdfbox.pdmodel.interactive.form.PDAppearance.insertGeneratedAppearance(PDAppearance.java:371)
> at org.apache.pdfbox.pdmodel.interactive.form.PDAppearance.setAppearanceValue(PDAppearance.java:281)
> at org.apache.pdfbox.pdmodel.interactive.form.PDVariableText.setValue(PDVariableText.java:131)
> Reason seems to be that PDApperance.getFontAndUpdateResources() returns null, in turn because the font dictionary for the DA of the field ("/Cour 11 Tf 0 g") is not present in the document.
