Description
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:
XmlPlannerBenchmarkFactory plannerBenchmarkFactory = new XmlPlannerBenchmarkFactory();
plannerBenchmarkFactory.configure("/pl/mskiba/dancingCobra/domain/BenchmarkConfig.xml");
PlannerBenchmark plannerBenchmark = plannerBenchmarkFactory.buildPlannerBenchmark();
plannerBenchmark.benchmark();
BenchmarkConfig.xml:

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:
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();
Everything works fine! Same problem, same XML file, same configuration, but with Drools Benchmarker it simply doesn't work.
