title: FireAllRules() and StartProcess() not producing effect
body: <p>hope someone can help me on this. So, I have some local bpmn processes that I imported from BPMS from RedHat. Now I am trying to execute them, as well as some .drl files, with no success on both tries. This is what I am trying:</p>
  
  <pre><code>     KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
       Resource ruleFile = ResourceFactory.newFileResource("src/main/resources/rules0.drl");
       Resource ruleFile1 = ResourceFactory.newFileResource("src/main/resources/rules0.drl");
       Resource process1 = ResourceFactory.newFileResource("src/main/resources/Process1.bpmn");
       kbuilder.add(ruleFile,ResourceType.DRL);
       kbuilder.add(ruleFile1,ResourceType.DRL);
       kbuilder.add(process1,ResourceType.BPMN2);
  
       KnowledgeBase kbase = kbuilder.newKnowledgeBase();
  
       kbase.addKnowledgePackages(kbuilder.getKnowledgePackages());                       StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
       ksession.fireAllRules();
       ksession.startProcess(process1.getSourcePath());
  </code></pre>
  
  <p>But I have tried also :</p>
  
  <pre><code>    KieServices kServices = KieServices.Factory.get();
      KieRepository kRepository = kServices.getRepository();
      KieFileSystem kFileSystem = kServices.newKieFileSystem();
       Resource ruleFile = ResourceFactory.newFileResource("src/main/resources/rules0.drl");
      kFileSystem.write(ResourceFactory.newClassPathResource("rules0.drl"));
      KieBuilder kBuilder = kServices.newKieBuilder(kFileSystem);
      kBuilder.add(ruleFile,ResourceType.DRL);
      kBuilder.buildAll();
  
  KieContainer kContainer =
      kServices.newKieContainer(kRepository.getDefaultReleaseId());
      KieBase kBase = kContainer.getKieBase();
      KieSession kisession = kBase.newKieSession();
      int tot = kisession.fireAllRules();
  
      System.out.println(""+tot);
  </code></pre>
  
  <p>totalRules is zero and the rule was never fired. In both cases, if I try to start processes(and only if) it will come to:</p>
  
  <p>Exception in thread "main" java.lang.AbstractMethodError: org.jbpm.bpmn2.BPMN2ProcessProviderImpl.configurePackageBuilder(Lorg/kie/internal/builder/KnowledgeBuilder;)V</p>
  
  <p>If I only try to fire rules then nothimg happens and tot is 0. The rules are simple rules that only execute a syso. Am I missing something here ? The rules are at src/main/resources/ on my maven project. Sorry for such a gigantic post!</p>
