With Oracle JDK 7u40 on Mac OS X 10.8, I get:

$ java -jar kawa-1.13.1.jar 
#|kawa:1|# (write (car (command-line)))
"java kawa-1.13.1.jar"

$ java kawa.repl
#|kawa:1|# (write (car (command-line)))
"java kawa.repl"

$ cat /tmp/test.scm 
(write (car (command-line)))
(newline)

$ java -jar kawa-1.13.1.jar -f /tmp/test.scm 
"java kawa-1.13.1.jar -f /tmp/test.scm"

$ java kawa.repl -f /tmp/test.scm 
"java kawa.repl -f /tmp/test.scm"

In other words, it seems to do what you'd expect.
