Buggy source:
public void seeProfile(String url,StructureDefinition p) throws FHIRException {
  if (Utilities.noString(url))   url=p.getUrl();
  if (!p.hasSnapshot() && p.getKind() != StructureDefinitionKind.LOGICAL) {
    if (!p.hasBaseDefinition())     throw new DefinitionException("String_Node_Str" + p.getName() + "String_Node_Str"+ p.getUrl()+ "String_Node_Str");
    StructureDefinition sd=fetchResource(StructureDefinition.class,p.getBaseDefinition());
    if (sd == null)     throw new DefinitionException("String_Node_Str" + p.getName() + "String_Node_Str"+ p.getUrl()+ "String_Node_Str"+ p.getBaseDefinition()+ "String_Node_Str");
    List<ValidationMessage> msgs=new ArrayList<ValidationMessage>();
    List<String> errors=new ArrayList<String>();
    ProfileUtilities pu=new ProfileUtilities(this,msgs,this);
    pu.sortDifferential(sd,p,url,errors);
    for (    String err : errors)     msgs.add(new ValidationMessage(Source.ProfileValidator,IssueType.EXCEPTION,"String_Node_Str" + err,ValidationMessage.IssueSeverity.ERROR));
    pu.generateSnapshot(sd,p,p.getUrl(),p.getName());
    for (    ValidationMessage msg : msgs) {
      if (msg.getLevel() == ValidationMessage.IssueSeverity.ERROR || msg.getLevel() == ValidationMessage.IssueSeverity.FATAL)       throw new DefinitionException("String_Node_Str" + p.getName() + "String_Node_Str"+ p.getUrl()+ "String_Node_Str"+ msg.getMessage());
    }
    if (!p.hasSnapshot())     throw new DefinitionException("String_Node_Str" + p.getName() + "String_Node_Str"+ p.getUrl()+ "String_Node_Str");
    pu=null;
  }
  if (structures.containsKey(p.getUrl()) && !allowLoadingDuplicates)   throw new DefinitionException("String_Node_Str" + p.getUrl());
  structures.put(p.getId(),p);
  structures.put(p.getUrl(),p);

}

Fixed version (ground truth):
public void seeProfile(String url,StructureDefinition p) throws FHIRException {
  if (Utilities.noString(url))   url=p.getUrl();
  if (!p.hasSnapshot() && p.getKind() != StructureDefinitionKind.LOGICAL) {
    if (!p.hasBaseDefinition())     throw new DefinitionException("String_Node_Str" + p.getName() + "String_Node_Str"+ p.getUrl()+ "String_Node_Str");
    StructureDefinition sd=fetchResource(StructureDefinition.class,p.getBaseDefinition());
    if (sd == null)     throw new DefinitionException("String_Node_Str" + p.getName() + "String_Node_Str"+ p.getUrl()+ "String_Node_Str"+ p.getBaseDefinition()+ "String_Node_Str");
    List<ValidationMessage> msgs=new ArrayList<ValidationMessage>();
    List<String> errors=new ArrayList<String>();
    ProfileUtilities pu=new ProfileUtilities(this,msgs,this);
    pu.sortDifferential(sd,p,url,errors);
    for (    String err : errors)     msgs.add(new ValidationMessage(Source.ProfileValidator,IssueType.EXCEPTION,p.getUserString("String_Node_Str"),"String_Node_Str" + err,ValidationMessage.IssueSeverity.ERROR));
    pu.generateSnapshot(sd,p,p.getUrl(),p.getName());
    for (    ValidationMessage msg : msgs) {
      if (msg.getLevel() == ValidationMessage.IssueSeverity.ERROR || msg.getLevel() == ValidationMessage.IssueSeverity.FATAL)       throw new DefinitionException("String_Node_Str" + p.getName() + "String_Node_Str"+ p.getUrl()+ "String_Node_Str"+ msg.getMessage());
    }
    if (!p.hasSnapshot())     throw new DefinitionException("String_Node_Str" + p.getName() + "String_Node_Str"+ p.getUrl()+ "String_Node_Str");
    pu=null;
