Here is a unit test you can add to PackageBuilderTest:
public void testAddPackage() throws IOException {
KnowledgeBuilder kbuilder =
KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newInputStreamResource(this.getClass().getResourceAsStream("mortgages_TEST.pkg")),
ResourceType.PKG);
KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
kbase.addKnowledgePackages(kbuilder.getKnowledgePackages());
StatefulKnowledgeSession session =
kbase.newStatefulKnowledgeSession();
}
The unit test uses the mortgages_TEST from guvnor, you need to add
mortgages_TEST.pkg to
src/test/resources/org.drools.compiler. I have attached the mortgages
test pkg to this email.
perfect, if only more bug reporting was like this :)

Try changing the code to this, let me know if it fixes the problem and
I'll apply to trunk. any chance you could send us a mini self
contained unit test for this bug?
public synchronized void addPackage(final Package newPkg) {
PackageRegistry pkgRegistry = this.pkgRegistryMap.get(
newPkg.getName() );
Package pkg = null;
if ( pkgRegistry != null ) {
pkg = pkgRegistry.getPackage();
}
if ( pkg == null ) {
pkg = newPackage( new PackageDescr( newPkg.getName() )
).getPackage();
}

if pkgRegistryMap is empty as it should probably be initially adding
a new package will cause a NPE.
This fuction assumes that there is always a package in the
packageRegistryMap.
I am getting a NPE when I am trying something like:
KnowledgeBuilder kbuilder =
KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newUrlResource("a valid
url"),
ResourceType.PKG);
thanks for any help
