Hi KeyClock Team,

I tried to set up the Keycloak server and its sample Restful service 'product database'.

All the setup steps was quite straightforward with the help of reference guide, but when i try to get the resouces behind /database/products, i can get the redirect login page and manage to login with the test account.but after all, i got a 'internal server error'.

Below is the exception showed in my server log, am i missing anything during my setup?
