I tried upgrading from 1.1.0-Alpha1 to 1.2.0.Beta1.jar. I get many errors that look like this:
18:35:32,990 ERROR [io.undertow.request] (default task-122) UT005023: Exception handling request to /auth/realms/abecorn/tokens/login
Also, I had to copy the themes folder from the dist appliance because the war distributable is missing the themes folder.
