[keycloak-user] Exception with User Storage SPI priority configuration

Hi,

I just implemented the User Storage SPI as replacement for our User Federation SPI.

Creating the User-Storage Provider works w/o errors, but not Priority value will be saved.
When updating the Provider with a value for Priority, it will fail with an exception (see below), updating the Provider without setting a value for Priority works.

Do I have to implement/configure something special to get it work?
I based my implementation on the user-storage-jpa-example, provided with Keycloak.
Or is it a general error? Should a create a Jira issue for it?


The exception/stack trace:
