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?

But has it been derived from Red Hat code? My understanding was that it's basically a fork of src/hotspot/share/utilities/bitMap.* ? Which is Oracle-copyrighted. Is that correct?
