Description of problem: java.time.LocalDate is a native class in java 1.8 but causes marshaling errors on the kie-execution server using both jaxb and Xstream. Did not verify yet in json. Version-Release number of selected component (if applicable): Needs to be addressed in 7.0.0 and beyond as these are native java classes in Java 1.8 How reproducible: Setting up a kie-server with a container that contains a rule that references a global of type java.time.LocalDate. Then using the following to build request to the kie-server: KieServicesConfiguration config = KieServicesFactory.newRestConfiguration(REST_ENDPOINT, REST_USERNAME, REST_PASSWORD); config.setMarshallingFormat(MarshallingFormat.XSTREAM); KieServicesClient client = KieServicesFactory.newKieServicesClient(config); RuleServicesClient ruleClient = client.getServicesClient(RuleServicesClient.class); List<Command<?>> commands = new ArrayList<Command<?>>(); LocalDate localdate = LocalDate.now(); commands.add(CommandFactory.newSetGlobal("today", localdate)); commands.add(CommandFactory.newFireAllRules()); CommandFactory.newBatchExecution(commands, , SESSION_NAME); ServiceResponse<String> results = ruleClient.executeCommands("validation",batchExecutionCommand); Steps to Reproduce: 1. Set Up remote kie-server with rules with a global of type java.time.LocalDate and uses global 2. Send request to kie server pragmatically with code above. 3. Actual results: Server registers the following error using XSTREAM marshalling: [org.kie.server.services.impl.KieContainerCommandServiceImpl] (http-localhost.localdomain/127.0.0.1:8080-4) Error calling container 'validation': java.lang.RuntimeException: Illegal class for global. Expected [java.time.LocalDate], found [java.time.Ser]. Client registers the following error using JAXB marshalling: javax.xml.bind.JAXBException: class java.time.LocalDate nor any of its super class is known to this context. Expected results: Rules are executes and response of Success is returned. Additional info: This was discussed on sme list and conclusion was to stick to java 6 classes for versions 6.x but needs to be addressed in 7.0
