Question about copyright: I guess this is pretty much "all new", but the code was derived from original code, and much of the public API was borrowed from original.  So I think maybe I should keep Red Hat copyright, and add Amazon copyright.  What do you advise?

Sorry.  I didn't look closely.  This was not derived from original code.  I wrote this blind to the original, and then I made changes under guidance of reviewers to harmonize the API with Oracle implementation of bitMap.  So I think your original comment about copyright is appropriate.
