> During object creation  "*StoreFileScanner*", it does not increase the 
> refCount whereas while close it decrements the reader refCount. This will 
> cause refCount to -1 and isReadReference method was returning true 
> (refCount.get() != 0 This is causing store file not to be deleted. This may 
> also cause issue in situation when some thread is holding a scanner but it 
> may actually be closed due to above bug. Impact of this would be really high. 
> Attatching patch for the fix which makes sure if reference is held either 
> thru getScanner method or constructor, ref is always updated. Patch also 
> contains a test which validates the issue.
