[xwiki-users] Export to PDF java.lang.NullPointerException on some pages (possibly if images are too big)
When trying to export PDF some (not all) page of my XWiki 7.2, I get an error in the log and the PDF is never generated. HTML export works fine. Here are the first lines from the error : Dec 2 09:37:07 xwiki01 server: java.lang.NullPointerException: Parameter alpha must not be null Dec 2 09:37:07 xwiki01 server: at org.apache.fop.pdf.AlphaRasterImage.<init>(AlphaRasterImage.java:57) ~[fop-1.1.jar:na] Dec 2 09:37:07 xwiki01 server: at org.apache.fop.pdf.AlphaRasterImage.<init>(AlphaRasterImage.java:71) ~[fop-1.1.jar:na] Dec 2 09:37:07 xwiki01 server: at org.apache.fop.render.pdf.ImageRenderedAdapter.setup(ImageRenderedAdapter.java:127) ~[fop-1.1.jar:na] Dec 2 09:37:07 xwiki01 server: at org.apache.fop.pdf.PDFDocument.addImage(PDFDocument.java:816) ~[fop-1.1.jar:na] Dec 2 09:37:07 xwiki01 server: at org.apache.fop.render.pdf.AbstractPDFImageHandler.handleImage(AbstractPDFImageHandler.java:46) ~[fop-1.1.jar:na] I can't say for sure that the size of the images in those pages is the cause of the export failure, but just before the stacktrace, I get a few WARN Dec 2 09:37:06 xwiki01 server: 2015-12-02 09:37:06,773 [ http://xwiki01:8080/xwiki/bin/export/White_Rabbit/Fabrication/GitLab+-+Manue... ] WARN o.a.f.a.FOUserAgent - Line 1 of a paragraph overflows the available area by 9000 millipoints.

Looks like http://jira.xwiki.org/browse/XWIKI-8274. From what I understand the image format is too recent for the old FOP 1.1 version we are still using. On Wed, Dec 2, 2015 at 10:02 AM, <[email protected]> wrote:

Ok, thanks I see that there is a reference to http://jira.xwiki.org/browse/XWIKI-12871 Is it really an objective of the 7.4 or might it be moved to another later release ? Can I do about it beside waiting for 7.4 to be released ? Can I upgrade a component myself as a workaround ?

Currently looking at it but no promise for 7.4 (this is not a small move and it was not exactly part of the roadmap).
Can I do about it beside waiting for 7.4 to be released ? Can I upgrade a component myself as a workaround ?
Not it this case since FOP 2.0 broke a few APIs used by XWiki as far as I can see.

Upgrade done. But not sure if it fix you issues since I can't find a way to reproduce it. If it's possible to you to provide on http://jira.xwiki.org/browse/XWIKI-8274 a XAR with a wiki page on which you have to issue that would be great.
