Error en ORACLE ENTERPRISE MANAGER CONSOLE

[JuanFer13]

Hola

Recientemente actualice mi PC de WINDOWS XP a WINDOWS 7 ULTIMATE 64 BITS, entro a mi Consola de Enterprise Manager versión 10.2.0 y cuando trato de conectarme ya a la base de datos luego de poner el respectivo usuario y la contraseña me bota el siguiente error:

java.lang.NullPointerException
