the class CollectionResourceWrapperIT method testGetCounterValueWithGap.

/**
      * Per bug report NMS-4244, multiple calls to the getCounter functionality on CollectionResourceWrapper used to pay
      * no mind of the actual time when samples were collected, instead assuming that it was the collection interval ago.
      * When a collection cycle fails (entirely or partly) and thresholded values weren't available, the counter value
      * was incorrectly calculated on the next succeeding cycle (taking the difference from the last successful 
      * collection and dividing by just a single collection interval.
