Hi Klaus Thanks, can you open an issue on JIRA at https://issues.apache.org/jira/browse/pdfbox and if possible attach the file as an SVN patch (see https://ariejan.net/2007/07/03/how-to-create-and-apply-a-patch-with-subversion/) via More > Attach Files.
We might want to add some similar code to the trunk as well as 1.8, but I’ll figure that out later.
