Hello,
While our plugin is working in Confluence 7.18, it can download a pdf file in the temp folder, it can not find the pdf while the plugin is working on 7.19 so it is getting a 404 not found error. When I look at the paths of the resource. They have same root path("confluence/temp") for both versions. Also, I can see generated pdf in the temp folder, it is the same in both of versions. There is no problem for generating pdf but the download link is not working.
