I'm not sure what and when is returned from

Is it unalisedPwd when it's not null and empty? Strange.

Originally it said

            if (unalisedPwd != null && "".equals(unalisedPwd));
               return unalisedPwd;

(with misleading indentation, but when condition was met then nothing happened and unalisedPwd was returned) which was then "corrected" with javaee/glassfish@12e76af.

Given it "worked" for 15 years, it's uncertain for me if this shall be modified, ignored or removed.
