Hi Sun,
> [snipped patch description] > Please help review the patch. Thanks. > [2. text/x-patch; > 0001-Fix-DISPLAY-error-on-exporting-org-with-plantuml-to-.patch]... Thanks for your patience. This looks quite straight-forward. I don't use or have plantuml so I'm in a poor position to test. However, I can use google, and it seems that -Djava.awt.headless=true just uses Java for some graphics operations which are normally delegated to the system graphics stack. This seems rather safe to me, and so I'd be inclined to take your word that this is a beneficial change and merge the patch. All the best, Timothy
