No error is reported even if rules are not loaded correctly due to inconsystency of Data Model.

Issue

When running Drools application developed by JBDS and it also has Data Model with the project which is inconsistent with the one referenced by rules in kjar, building kieBase complete without any error/warning message even if no rule is loaded due to inconsistency of data model

Here is snippet of code.

        String groupId      = "com.sample";
        String artifactId   = "Test";
        String versionId    = "RELEASE";

        System.out.println("*** debug *** groupId    = "+ groupId);
        System.out.println("*** debug *** artifactId = "+ artifactId);
        System.out.println("*** debug *** versionId  = "+ versionId);


    KieServices ks = KieServices.Factory.get();

    ReleaseId releaseId = ks.newReleaseId( groupId, artifactId, versionId );
        KieContainer kContainer = ks.newKieContainer( releaseId );
        KieSession kSession =  kContainer.newKieSession();

        int ruleCount = 0;
    for (KiePackage kiePackage : kSession.getKieBase().getKiePackages())
    {
         ruleCount += kiePackage.getRules().size();
    }

        System.out.println( ruleCount + " rules(s) loaded");

If this run with BRMS6.0.3 libraries, no message is shown even if no rules is loaded.

*** debug *** groupId    = com.sample
*** debug *** artifactId = Test
*** debug *** versionId  = RELEASE
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
0 rule(s) loaded 

But if this run with BRMS6.1.0 (and later) libraries, the following error message is shown as expected.

*** debug *** groupId    = com.sample
*** debug *** artifactId = Test
*** debug *** versionId  =  RELEASE
