Places where you see "[ Masked ]" means that those packages haven't been 
tested sufficiently to green-light them for production use under x86_64, 
as distinct from "will make your dog explode and burn your house down."  
But as you can see, the different JREs have wide-ranging package sizes, 
whatever that implies for post-installation footprint.
