Hi all,

In the sources for klass.hpp [1] there is a reference to some discussion

// The fields _super_check_offset, _secondary_super_cache, _secondary_supers
// and _primary_supers all help make fast subtype checks. See big discussion
// in doc/server_compiler/checktype.txt

This reference is present in JDK 11 latest sources however this comment 
dates back to as far as I can trace (1.7).
I assume this link is to some internal wiki page. Is it possible to make 
it publicly visible somehow? It is understood that the content is likely 
to be outdated.
