> Rumen's processing of FSImage logs reports the value of "IS_COMPRESSED" incorrectly as "-39" (or whatever the image-version is).
> The problem is in ImageLoaderCurrent, where the FSIMAGE_COMPRESSION node is visited using the imageVersion value instead of the value of isCompressed.) A fix is forthcoming.
