Thanks for doing this.

src/hotspot/share/classfile/moduleEntry.hpp
    'M' is meant to be lower case in "unnamed Module", right?

src/hotspot/share/interpreter/linkResolver.cpp
+      "tried to access method %s.%s%s from class %s (%s%s%s)",

Since you are on this file, it may read better if rephrased to:
   "class %s tried to access method %s.%s%s (%s%s%s)",

Thanks
Mandy
