decision table building => NPE
------------------------------

                 Key: JBRULES-3005
                 URL: https://issues.jboss.org/browse/JBRULES-3005
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: drools-compiler (expert)
    Affects Versions: 5.2.0.M2
            Reporter: Wolfgang Laun
            Assignee: Mark Proctor


kBuilder.add( resource, resourceType.DTABLE ); results in a NPE:

Exception in thread "main" java.lang.NullPointerException
       at org.drools.decisiontable.DecisionTableProviderImpl.compileStream(DecisionTableProviderImpl.java:26)
       at org.drools.decisiontable.DecisionTableProviderImpl.loadFromInputStream(DecisionTableProviderImpl.java:19)
       at org.drools.compiler.DecisionTableFactory.loadFromInputStream(DecisionTableFactory.java:18)
       at org.drools.compiler.PackageBuilder.addKnowledgeResource(PackageBuilder.java:497)
       at org.drools.builder.impl.KnowledgeBuilderImpl.add(KnowledgeBuilderImpl.java:28)
       at rss.drools.setup.Application.setup(Application.java:47)

Notice that a simple 
    DecisionTableConfiguration dtConf = KnowledgeBuilderFactory.newDecisionTableConfiguration();
    kBuilder.add( resource, resourceType, dtConf );
is not sufficient, the DecisionTableConfiguration still needs a DecisionTableInputType

Expected. there is a reasonable default DecisionTableConfiguration with DecisionTableInputType.XLS being set.

The simple call worked fine in 5.1.
