Description

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);
