Crowd 2.2 Rest API resource /user/mail/usernames?email=EMAIL always returns 204 status

Hello, I'm developing an app that talks to crowd 2.2.2 rest api. I noticed that a post to the following rest api resource returns 204 regardless of whether the email is found in the system:

/rest/usermanagement/latest/user/mail/usernames?email=valid_email => returns 204
/rest/usermanagement/latest/user/mail/usernames?email=invalid_email => returns 204, but should return 404 according to the documentation here: https://developer.atlassian.com/display/CROWDDEV/Crowd+REST+Resources.

I'm sure this is extremely low priority, and I can work around by first searching for the email to see if I get any search results. But just wanted to let you all know about the minor bug.

Thanks!
