I disagree that the check is redundant. It is still a good idea to check
if plantuml jar exists on server itself. Another question is how to make
`file-exists-p' work with TRAMP.

Your patch will break legitimate check for people running plantuml
locally. A better way would be checking default-directory and if we are
in a remote server, using appropriate check working over TRAMP.

Best,
