[keycloak-user] Authorization settings can't be exported more than once on 3.1.0.Final

[Stephane Granger]

I am running into a weird issue.  After creating a client which uses the
Authorization settings, the settings can only be exported 1 time.
Rebooting the key cloak server doesn't clear the problem.

Steps to reproduce.

Create TEST realm

Create TEST client, make sure the Authorization Enabled slider is set to
ON, click save.

Create the following Roles for the client
role1
role2
role3

Go on the Authorization tab
create 3 policies: policy1, policy2, policy3 with corresponding required
 role1...3 from the TEST client

create Authorization Scopes: scope1, scope2, scope3

create Resources: resource1 with scope2, resource2/scope2 and
resource3/scope3

finally, create the permissions
resource based: permission1/resource1/policy1
resource based: permission2/resource2/policy2
scope based: permission3/scope3/policy3

On the Authorization tab of the TEST client, click on the Export button.
This will work.
Navigate back to a different realm, and back again to the Authorization tab
of the TEST client, try exporting again, this time it will fail.
Restarting the Keycloak server does not clear the problem.


Here are the logs:
