-------------------------------------------

I fixed 735113 in org.drools.builder.impl.KnowledgeBuilderImpl#add were it was more appropriate, but did not make any changes related to this issue.

> 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.
