> When adding a change-set which contains a decision table to a KnowledgeAgent I receive the following error:
> 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:16)
> 	at org.drools.compiler.PackageBuilder.addKnowledgeResource(PackageBuilder.java:508)
> 	at org.drools.builder.impl.KnowledgeBuilderImpl.add(KnowledgeBuilderImpl.java:25)
> 	at org.drools.agent.impl.KnowledgeAgentImpl.rebuildResources(KnowledgeAgentImpl.java:386)
> 	at org.drools.agent.impl.KnowledgeAgentImpl.applyChangeSet(KnowledgeAgentImpl.java:120)
> 	at org.drools.agent.impl.KnowledgeAgentImpl.applyChangeSet(KnowledgeAgentImpl.java:109)
> 	at org.drools.bug.AgentDecisionTableBug.main(AgentDecisionTableBug.java:12)
> I tested with 5.0.1 and 5.1.0.SNAPSHOT.  I looked into the code a little and it appears that KnowledgeAgentImpl.rebuildResources does not parse the DecisionTable's configuration and pass it to the overloaded KnowledgeBuilderImpl.add method.
