Problema dll Delphi com jna

Olá amigos, estou tendo problemas com uma dll em java, em Delphi ela funciona beleza, mas, meus conhecimentos em Delphi são muitos limitados, por isso resolvi criar essa Dll e usar com java. Acredito que o problema seja com os tipos Variant e OleVariant, pois testei uma simples MessageBox e funcionou.

Código da Dll.

library MacroParaJava;


uses
  SysUtils,
  ComObj,
  windows,
  Variants,
  Classes;

   var
   Sess0,
   Sistema,
   Sessions: OleVariant;


//______________________________________________________________________________

                          // Conectar ao STC

 procedure conectarSTC;  stdcall;
    begin

  Sistema := CreateOleObject('EXTRA.System');
  Sessions:= Sistema.Sessions;
  Sess0   := Sistema.ActiveSession ;
  MessageBoxA(0,PAnsiChar('Criado Sessão!'),PAnsiChar('Aviso'),0);
    
    end;
//______________________________________________________________________________


       // Mover para uma posição na tela conforme argumentos informados
 procedure Mover(linha, coluna:Integer); stdcall;
    begin

  Sess0.Screen.MoveTo (linha, coluna);

    end;
//______________________________________________________________________________

                      // Tempo entre uma tela

 procedure aguardar; stdcall;
    begin

   while(Sess0.Screen.OIA.XStatus = 5) do
   begin
   end;
    end;

//______________________________________________________________________________

            // Enviar uma tecla conforme argumento informado

procedure enviarTecla(tecla:String); stdcall;
    begin
 Sess0.Screen.SendKeys(tecla);
    end;

//______________________________________________________________________________

                   // Copiar uma área da Tela

 function copiarAreaTela(linhaDe, colunaDe,linhaAte,colunaAte:Integer): String;  stdcall;
  begin

    Result:= Sess0.Screen.Area(linhaDe,colunaDe,linhaAte,colunaAte);
  end;


//______________________________________________________________________________

                   // Desconectar

 procedure desconectarSTC;  stdcall;
  begin
    Sess0    :=Unassigned;
    Sessions :=Unassigned;
    Sistema  :=Unassigned;
  end;



                    // Exportar Funções e Procedimentos
Exports
test,
conectarSTC,
Mover,
aguardar,
enviarTecla,
desconectarSTC,
copiarAreaTela;

begin
end.

Interface JNA com apenas um método para teste.

import com.sun.jna.Library;


public interface InterfaceJna extends Library{   
    
    
    public void conectarSTC();
  
}

Código da classe onde é chamado.

InterfaceJna ij = (InterfaceJna) Native.loadLibrary("MacroParaJava.dll", InterfaceJna.class);
   
    ij.conectarSTC();
