apache.pdfbox.pdfparser.XrefTrailerResolver flood in log

My log is flooded with

WARN [scheduler_Worker-1] [apache.pdfbox.pdfparser.XrefTrailerResolver] setStartxref Did not found XRef object at specified startxref position 12345

Is it possible to resolve this somehow? And what this warning means?

This widget could not be displayed.

It seems that I was able to fix this by adding line


to /confluence/WEB-INF/classes/log4j.properties and restarting Confluence.

To verify:

  • upload pdf file to page and you will see such WARN in log
  • make changes in log4j and try to upload another pdf file. Now there are no such WARNs in log
