Description

I noticed this problem while I am working on porting HIVE to work on windows. Hive is attempting to create this class object to validate the file format and end up with resource leak. Because of this leak, we can’t move, rename or delete the files on windows when there is an open file handle whereas in UNIX we can perform all these operation with no issues even with open file handles.

Please suggest me if you similar issues in any other places.
