Describe the bug

I just downloaded the nightly build, started the server, and went to http://localhost:8180

Instead of the welcome page for adding the initial admin user, I got:
!image

Clicking on the link didn't help.

Also, adding the environment variables didn't fix the problem. Even with these set, I still can't log in.
```
C:\keycloak-nightly\keycloak-999.0.0-SNAPSHOT\bin>set |grep BOOTSTRAP
KC_BOOTSTRAP_ADMIN_PASSWORD=admin
KC_BOOTSTRAP_ADMIN_USERNAME=admin
```

This is on Windows, so it could be a Windows-only issue.
