[rules-dev] decision table building => NPE

[Wolfgang Laun]

After pull from upstreammaster and mvn.

This used to work not so long ago; easy to follow:

KnowledgeBuilderImpl:

    public void add(Resource resource, ResourceType type) {
        pkgBuilder.addKnowledgeResource( resource, type, null )  ;
// Note the null!
    }

PackageBuilder:

                DecisionTableConfiguration dtableConfiguration =
(DecisionTableConfiguration) configuration;

                String string =
DecisionTableFactory.loadFromInputStream( resource.getInputStream(),

   dtableConfiguration );    // the null thing!

DecisionTableFactory:

    public static String loadFromInputStream(InputStream is,
DecisionTableConfiguration configuration) {

        return getDecisionTableProvider().loadFromInputStream( is,
configuration );     // the null thing!
    }


DecisionTableProviderImpl:

   public String loadFromInputStream(InputStream is,
                                      DecisionTableConfiguration
configuration) {

        return compileStream( is,
                              configuration );    // the null thing!
    }

    private String compileStream(InputStream is,
                                 DecisionTableConfiguration configuration) {
        SpreadsheetCompiler compiler = new SpreadsheetCompiler();
        switch ( configuration.getInputType() ) {
                           // NPE
