As far as you touching this.

Is it possible to change all native methods in these two classes to have
0 at the end of name?

i.e. readBytes => readBytes0

it's pure cosmetic, but fairly simplify core dump reading and later

Changing the public methods to be to non-native and instead calling private native methods simplifies instrumentation.
