When I try to add a data source (or xa datasource) via the web console and I push the "Test Connection" button the web console shows "Successfully created JDBC connection". But if push then the "Done" button it shows the message "unknown error" (Internal Server Error, "response-headers" => {"process-state" => "reload-required"}. and the datasouce is not added.  The datasource is only added if I skip the "Test Connection" button.
