Hi I just found a bug in ob-plantuml.el (if (string= (file-name-extension out-file) "svg") "-tsvg" "") needs to be changed to (if (string= (file-name-extension out-file) "svg") " -tsvg" "") as otherwise, when using the file name extension .svg, the -tsvg is concatenated behing -jar without space producing an error message.
