PackageBuilder.java at line 688:

public synchronized void addPackage(final Package newPkg) {
Package pkg = this.pkgRegistryMap.get( 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
