Fixed version (ground truth):
protected void logOutput(Message message,String... targetFlowStepIds){
  Collection<String> targetStepIds=targetFlowStepIds != null ? Arrays.asList(targetFlowStepIds) : Collections.emptyList();
  int threadNumber=ThreadUtils.getThreadNumber();
  for (  StepRuntime targetRuntime : targetStepRuntimes) {
    boolean forward=targetStepIds == null || targetStepIds.size() == 0 || targetStepIds.contains(targetRuntime.getComponentContext().getFlowStep().getId());
    if (forward) {
      componentContext.getExecutionTracker().log(threadNumber,LogLevel.INFO,componentContext,String.format("String_Node_Str",message.getHeader().getSequenceNumber(),message.getHeader().isUnitOfWorkLastMessage()));
      Serializable payload=message.getPayload();
      if (payload instanceof List) {
        @SuppressWarnings("String_Node_Str") List<Object> list=(List<Object>)payload;
        for (        Object object : list) {
          if (object instanceof EntityData) {
            Row rowData=new Row(0);
            try {
              rowData=componentContext.getFlowStep().getComponent().toRow((EntityData)object,true);
            }
 catch (            Exception e) {
            }
            componentContext.getExecutionTracker().log(threadNumber,LogLevel.INFO,componentContext,String.format("String_Node_Str",rowData));
          }
 else {
            componentContext.getExecutionTracker().log(threadNumber,LogLevel.INFO,componentContext,String.format("String_Node_Str",object));
