VUGen - Java Protocol - lr.eval_string does not appear to be working.

JAVA protocol. - lr.eval_string is displaying the param name and not value. Any idea how to fix this issue in JAVA protocol.

*****SCRIPT******

lr.message("Get remote user " lr.eval_string("<REMOTE_USER>"));

******Output *********:
