Buggy source:

  dlog(LogCategory.PROGRESS,"String_Node_Str" + type);
  for (  FetchedFile f : fileList) {
    for (    FetchedResource r : f.getResources()) {

        if (!r.isValidated())         validate(f,r);
        if (r.getResource() == null)         try {
          r.setResource(parse(f));
          r.getResource().setUserData("String_Node_Str",r.getElement());

Fixed version (ground truth):
private void load(String type) throws Exception {
  dlog(LogCategory.PROGRESS,"String_Node_Str" + type);
  for (  FetchedFile f : fileList) {
    for (    FetchedResource r : f.getResources()) {
      if (r.getElement().fhirType().equals(type)) {
        dlog(LogCategory.PROGRESS,"String_Node_Str" + r.getId());
        if (!r.isValidated())         validate(f,r);
        if (r.getResource() == null)         try {
          r.setResource(parse(f));
          r.getResource().setUserData("String_Node_Str",r.getElement());
        }
 catch (        Exception e) {
          throw new Exception("String_Node_Str" + f.getName() + "String_Node_Str"+ e.getMessage(),e);
        }
        MetadataResource bc=(MetadataResource)r.getResource();
        boolean altered=false;
        if (businessVersion != null) {
          if (!bc.hasVersion()) {
            altered=true;
          }
 else           if (!bc.getVersion().equals(businessVersion))           System.out.println("String_Node_Str" + f.getName() + "String_Node_Str"+ bc.getVersion()+ "String_Node_Str"+ businessVersion);
          bc.setVersion(businessVersion);
        }
        if (!bc.hasDate()) {
          altered=true;
          bc.setDateElement(new DateTimeType(execTime));
        }
        if (!bc.hasStatus()) {
          altered=true;
          bc.setStatus(PublicationStatus.DRAFT);
        }
        if (altered)         r.setElement(convertToElement(bc));
        igpkp.checkForPath(f,r,bc);
