Buggy source:
@Override public void handle(final Message inputMessage,final ISendMessageCallback callback,boolean unitOfWorkBoundaryReached){
  NamedParameterJdbcTemplate template=getJdbcTemplate();
  Map<String,Object> paramMap=new HashMap<String,Object>();
  int inboundRecordCount=1;
  ArrayList<EntityData> inboundPayload=null;
  if (!(inputMessage instanceof ControlMessage)) {
    inboundPayload=inputMessage.getPayload();
    if (inboundPayload != null) {
      inboundRecordCount=inboundPayload.size();
    }
  }
  ArrayList<EntityData> outboundPayload=null;
  for (int i=0; i < inboundRecordCount; i++) {
    if (inboundPayload != null && inboundPayload.size() > i && inboundPayload.get(i) instanceof EntityData) {
      setParamsFromInboundMsgAndRec(paramMap,inputMessage,inboundPayload.get(i));
    }

      setParamsFromInboundMsgAndRec(paramMap,inputMessage,null);
    }
    ResultSetToEntityDataConverter resultSetToEntityDataConverter=new ResultSetToEntityDataConverter(inputMessage,callback,unitOfWorkBoundaryReached);
    for (    String sql : getSqls()) {
      String sqlToExecute=FormatUtils.replaceTokens(sql,getComponentContext().getFlowParametersAsString(),true);
      log(LogLevel.INFO,"String_Node_Str" + sqlToExecute);
      resultSetToEntityDataConverter.setSqlToExecute(sqlToExecute);
      outboundPayload=template.query(sqlToExecute,paramMap,resultSetToEntityDataConverter);
    }
  }
  if (outboundPayload != null && outboundPayload.size() > 0) {
    callback.sendMessage(null,outboundPayload,unitOfWorkBoundaryReached);
  }
}

Fixed version (ground truth):
@Override public void handle(final Message inputMessage,final ISendMessageCallback callback,boolean unitOfWorkBoundaryReached){
  NamedParameterJdbcTemplate template=getJdbcTemplate();
  Map<String,Object> paramMap=new HashMap<String,Object>();
  int inboundRecordCount=1;
  ArrayList<EntityData> inboundPayload=null;
  if (!(inputMessage instanceof ControlMessage)) {
    inboundPayload=inputMessage.getPayload();
    if (inboundPayload != null) {
      inboundRecordCount=inboundPayload.size();
    }
  }
  ArrayList<EntityData> outboundPayload=null;
  for (int i=0; i < inboundRecordCount; i++) {
    if (inboundPayload != null && inboundPayload.size() > i && inboundPayload.get(i) instanceof EntityData) {
      setParamsFromInboundMsgAndRec(paramMap,inputMessage,inboundPayload.get(i));
    }
 else {
      setParamsFromInboundMsgAndRec(paramMap,inputMessage,null);
    }
    ResultSetToEntityDataConverter resultSetToEntityDataConverter=new ResultSetToEntityDataConverter(inputMessage,callback,unitOfWorkBoundaryReached);
    for (    String sql : getSqls()) {
      String sqlToExecute=FormatUtils.replaceTokens(sql,getComponentContext().getFlowParametersAsString(),true);
      log(LogLevel.INFO,"String_Node_Str" + sqlToExecute);
      resultSetToEntityDataConverter.setSqlToExecute(sqlToExecute);
      outboundPayload=template.query(sqlToExecute,paramMap,resultSetToEntityDataConverter);
    }
  }
  if (outboundPayload != null && outboundPayload.size() > 0) {
    callback.sendMessage(null,outboundPayload,unitOfWorkBoundaryReached);
    messageSent=true;
  }
  if (!messageSent && unitOfWorkBoundaryReached) {
    callback.sendMessage(null,new ArrayList<>(),true);
  }
