"access" in the package/class name does look a bit strange, and could easily get mixed up with the package and classes that are used for shared secrets. I don't think jdk.internal.util.ByteArrays would look out of place. Hopefully it won't need to be exported to many other modules as we need to keep the qualified exports to a minimum.
