My comments are nits. Generally, this PR looks good to me. 
I am not a reviewer. We still need other reviewers to approve it.

src/hotspot/share/code/codeCache.cpp line 109:

> 107:   void print(const char* title) const {

> 109:     {

better stick with the existing codestyle.  they always use if (cond) { and else {

src/hotspot/share/code/codeCache.cpp line 1497:

current code style prefer auto& stub.  same as 1486 1487 lines, asterisk associates with type.
