Benchmarker gives ConversionException because the default ProblemIO doesn't use a default XStream instance ---------------------------------------------------------------------------------------------------------- Key: JBRULES-3611 URL: https://issues.jboss.org/browse/JBRULES-3611 Project: Drools Issue Type: Enhancement Security Level: Public(Everyone can see) Components: drools-planner Affects Versions: 5.4.0.Final Environment: Ubuntu 12.04, Eclipse Juno, joda-time-2.1, xstream-1.4.3 Reporter: Marcin Skiba Assignee: Geoffrey De Smet Priority: Minor Labels: Benchmark, Drools Old title: Benchmark doesn't work with Joda datetime API My problem's domain uses Joda's DateTime and Duration classes. After starting a benchmark I'm getting an exception. See below: Code running the benchmark: {quote} XmlPlannerBenchmarkFactory plannerBenchmarkFactory = new XmlPlannerBenchmarkFactory();

org.joda.time.chrono.ISOChronology. In addition - if I run the following code: {quote} XStream xStream = new XStream(); Schedule problem = (Schedule) xStream.fromXML(new FileReader("/home/marcin/workspace/DancingCobra/src/main/resources/pl/mskiba/dancingCobra/domain/testProblems/Problem.xml")); SolverFactory solverFactory = new XmlSolverFactory("/pl/mskiba/dancingCobra/domain/scheduleSolverConfig.xml"); Solver solver = solverFactory.buildSolver(); solver.setPlanningProblem(problem); solver.solve(); {quote} Everything works fine! Same problem, same XML file, same configuration, but with Drools Benchmarker it simply doesn't work.
