Looking at patch:
... not a show stopper but better to list individual imports than use '*'.
This has to be public?
So it can be picked up by compaction code?
And these need to be public too for same reason?
In Store there are imports but they are not used?
Yeah, why you making stuff public in StoreFile? So can be reached from compaction package?
Should StoreUtils be public? Should it be private to this package?
Patch is good. Anything that can be done about reaching between packages and opening up methods that were previously package protected?
The small stuff in the above I can address on commit.
