[rules-dev] decision table building => NPE
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
Exception in thread "main" java.lang.NullPointerException
