The 8.3 driver is returning this as Integer[] instead of the primitive 
int[] because the server allows null values in arrays.  While null array 
elements are possible in the server since 8.2, the driver didn't get 
updated until 8.3.  You can change your code or provide the 
"compatible=8.2" URL parameter to your connection URL.
