Upgrade Jackson dependencies. ----------------------------- Key: DROOLS-2475 URL: https://issues.jboss.org/browse/DROOLS-2475 Project: Drools Issue Type: Bug Reporter: Petar Tahchiev Assignee: Maciej Swiderski Priority: Critical Hello, I'm not sure this is the right place to report this, but I couldn't find a better one. In my project I'm using: {code} <dependency> <groupId>org.kie.server</groupId> <artifactId>kie-server-jms</artifactId> <version>7.7.0.Final</version> </dependency> {code} and I believe you guys are using jackson version 2.8.9: https://github.com/kiegroup/kie-soup/blob/master/pom.xml#L56 which is already 1 year old. In my app some third-party dependencies are bringing jackson 2.9.5 and because of this mismatch I get the following exception when I run my app: {code} Caused by: java.lang.NoSuchMethodError: com.fasterxml.jackson.databind.SerializationConfig.with(Lcom/fasterxml/jackson/databind/AnnotationIntrospector;)Lcom/fasterxml/jackson/databind/SerializationConfig; at org.kie.server.api.marshalling.json.JSONMarshaller.configureMarshaller(JSONMarshaller.java:153) at org.kie.server.api.marshalling.json.JSONMarshaller.<init>(JSONMarshaller.java:128) at org.kie.server.api.marshalling.BaseMarshallerBuilder.build(BaseMarshallerBuilder.java:43) at org.kie.server.api.marshalling.MarshallerFactory.getMarshaller(MarshallerFactory.java:52) at org.kie.server.client.impl.AbstractKieServicesClientImpl.<init>(AbstractKieServicesClientImpl.java:83) at org.kie.server.client.impl.KieServicesClientImpl.<init>(KieServicesClientImpl.java:71) at org.kie.server.client.KieServicesFactory.newKieServicesClient(KieServicesFactory.java:101) at com.nemesis.platform.module.ruleservices.config.RuleServicesModuleAutoConfiguration.defaultKieServicesClient(RuleServicesModuleAutoConfiguration.java:160) {code}
