New subject: [JBoss JIRA] (JBRULES-3611) Benchmarker gives serialization error because the default ProblemIO doesn't use a default XStream instance

Friday, 31 August 2012

Marcin Skiba created JBRULES-3611:
-------------------------------------

             Summary: Benchmark doesn't work with Joda datetime API
                 Key: JBRULES-3611
                 URL: https://issues.jboss.org/browse/JBRULES-3611
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: drools-planner
    Affects Versions: 5.4.0.Final
         Environment: Ubuntu 12.04, Eclipse Juno
            Reporter: Marcin Skiba
            Assignee: Geoffrey De Smet

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();
plannerBenchmarkFactory.configure("/pl/mskiba/dancingCobra/domain/BenchmarkConfig.xml");
PlannerBenchmark plannerBenchmark = plannerBenchmarkFactory.buildPlannerBenchmark();
plannerBenchmark.benchmark();
{quote}

After running this code I'm getting:

I can see that there is a problem with 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.
