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
