Hi, What are correct Maven settings to get keycloak-admin-client working on Wildfly 10 From command line client it works with following below. When using same code in Wildfly with most recent keycloak module execution fails with following Caused by: javax.ws.rs.client.ResponseProcessingException: javax.ws.rs.ProcessingException: com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "access_token" (class org.keycloak.representations.AccessTokenResponse), not marked as ignorable (9 known properties: "notBeforePolicy", "otherClaims", "tokenType", "token", "expiresIn", "sessionState", "refreshExpiresIn", "idToken", "refreshToken"]) at [Source: org.apache.http.conn.EofSensorInputStream@9d6aba2; line: 1, column: 18] (through reference chain: org.keycloak.representations.AccessTokenResponse["access_token"]) I got that fixed in command line example by changing jackson provider to resteasy-jackson2-provider <dependency> <groupId>org.keycloak</groupId> <artifactId>keycloak-core</artifactId> <version>3.4.2.Final</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.keycloak</groupId> <artifactId>keycloak-adapter-core</artifactId> <version>3.4.2.Final</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.keycloak</groupId> <artifactId>keycloak-common</artifactId> <version>3.4.2.Final</version> </dependency> <dependency> <groupId>org.keycloak</groupId> <artifactId>keycloak-admin-client</artifactId> <version>3.4.2.Final</version> </dependency> <dependency> <groupId>org.jboss.resteasy</groupId> <artifactId>resteasy-client</artifactId> <version>3.0.24.Final</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.jboss.resteasy</groupId> <artifactId>resteasy-jackson2-provider</artifactId> <version>3.0.24.Final</version> <scope>provided</scope> </dependency> .t
