> In Execute method of GetValuesHandler, if the array object can't be retrieved from the
MapFromObjectID method, the value for it would be null. 
> Then, in the following JNI method, a null value passed to it would definitely result
in a crash. To solve the problem, we should throw an exception to notify the upper level method
that "GetValues: ReadArrayID() returned NULL".
> jclass arrObjClass = jni->GetObjectClass(arrayObject);
