Hi,

i have got an error in code when using regex-split,
here is the code tested here at REPL in kawa 2.1:

(require 'regex)

(define wds-url "http://ad.usno.navy.mil/wds/Webtextfiles/wdsnewref.txt")
(define wds-data-str &<{&[wds-url]})  ;; could take a few seconds to GET file
(define wds-data-str-split (regex-split wds-data-str (string #\return)))

result in this error at some point of splitting:

                  ^

        at kawa.repl.processArgs(repl.java:687)
        at kawa.repl.main(repl.java:793)

also tested it with #\linefeed and same error, also tested with " " and "A" : error

i did not look in the contain of the file and i will do it,but anyway the result should not be an error?
does the newest version of kawa give a different result?

Regards,
Damien
