Merchant UI Logo Image Won't Load If There's A Hyphen In Realm Name

If the subdomain of a subscriber contains a hyphen, the logo image for the merchant UI isn't loading.

To reproduce, create a realm with a hyphen, e.g. "ntt-tp", and following the skinning process as outlined here:
http://kbase.ri.thesearchagency.com/index.php/AdMax_Local_-_Merchant_UI

The logo will not appear on the login page, nor on the application page once logged in.

This is due to the image.jsp file having a "filterRealm" method that makes use of a regex pattern that isn't allowing hyphens in the domain name. The offending line is:

Pattern theRealmFilter = Pattern.compile("(?:(?:[\\w]{1,}\\.){0,}[\\w]{1,})$");

To fix the code, change the line to:

Pattern theRealmFilter = Pattern.compile("(?:(?:[\\w-]{1,}\\.){0,}[\\w-]{1,})$");

Workaround prior to code fix:

Do these steps on the tomcat server. Note this example assumes the realm name is "ntt-tp", and it's setting up an alias called "ntttp" that the image.jsp file will be told to use. Obviously change those names to fit the situation.

1) cd /usr/local/tsa/ui/com/thesearchagency/admaxlocal/merchant/client/realms/

2) sudo ln -s ntt-tp ntttp

3) sudo vi ntt-tp/css/overrides.css

4) Append &realm=ntttp to the end of the image url
.aml-header .aml-headerLogo .aml-headerLogoImage,
.aml-loginHeader .aml-loginHeaderLogo .aml-loginHeaderLogoImage
{
background: url('image.jsp?img=logo.png&realm=ntttp') no-repeat center center transparent;

5) Save file

This will fool the image.jsp file into using a realm name that doesn't have a dash in it.
