A function receives a list of arguments and `interactive' is supposed to
get a list (or a string which is interpreted according its spec).  So
this should do:

(defun run-java-main-method (mainClass)
  (interactive
   (list (completing-read "Run main method: " (get-main-method-list))))
  (message "Read %s" mainClass))

Bye,
