Kirk Lund updated GEODE-2012:
-----------------------------
Description:
If a given ResourceType has no Resource instances at the same time that a
statistics archive file is created by rolling, then the ResourceType is not
written to the archive file. If a later Resource instance for that type is
created, it will be written to the archive file without a ResourceType,
effectively corrupting that file so that it cannot be read.
Steps required to test this bug:
1) create resource instance of new type
2) sample so that resource instance and type are written to gfs
3) close resource instance so no instances exist of that type
4) sample
5) roll gfs archive
6) sample
7) create new resource instance of same type
8) sample
9) verify that resource instance and type were both written to gfs

Attempting to read the corrupted statistics archive file will result in a
NullPointerException (GEODE-2013).

The resulting gfs archive file after #5 contains a resource instance with no
corresponding resource type. Attempting to read the file in with
StatArchiveReader will throw a NullPointerException (GEODE-2013).
