After upgrading from 15.0.2 to 15.1.0 we get an Internal Server Error while trying to login as users. Admin Login ist working.
First of all, after downgrading again the problem is gone, so there is no urgent need for help.
Our user database is in MS AD and the LDAP connection test is working, but the authentication test fails. From the server log i got the following error:
2021-12-16 07:05:08,865 ERROR [org.keycloak.services.error.KeycloakErrorHandler] (default task-16) Uncaught server error: java.lang.NoSuchMethodError: java.nio.ByteBuffer.clear()L
