crowd base URL change needed - wrong URL used in password reset link mail

Hello.
We use Jira, Confl. and Crowd with SSO installed on different server. We use http proxy to provide all services under the same URL and port for the user.
Than if a password reset is requested the mail contains an URL with "localhost:9095" inside. We need to change those provided prefix to the real server URL due to the provided link is not valid. We miss a field for changing the base URL, like in Jira and Confluence.
It doesn't fixed this error if we change all files on the server containing the "localhost" base URL to the real URL.
The mail template only contains a "$resetlink" variable which seems JAVA hard coded.
Thanks.
