title: Getting error code 4220 with null SQL State
body: <p>I'm getting error code -4220 with null SQL State .the SP "XXXXX" contain VARGRAPHICS data type. Below is complete exception stack trace. SP is executing properly, the error is coming while reading output parameter i.e. execute method called successfully but getString method is giving error.</p>
  
  <p>Even if I'm trying to access any method to get output parameter value, error is coming. Just FYI, I tried with latest version of db2 driver but still error persist.</p>
