The flycheck-plantuml is by default configured to always run plantuml via "java". This only works with a downloaded plantuml. However, I would prefer to have plantuml installed via my package manager (fedora/dnf). A locally installed PlantUML executable is already detected by default for normal use (export/preview), we can also use it for flycheck. If plantuml is downloaded using plantuml-download-jar, this jar is still used by default (see setq plantuml-exec-mode), so this should not affect previous setups.
