C files and their Mapping(s)

[mr rupplin]

Hello.

Thanks for taking time.  We had a quick question about the Java to C mappings in the JDK.  For instance the System.java has a corresponding System.c and even a System.o.

We find these without too much problem.  However many of the "core" packages (corba, nashorn, jaxp, jaxws) do not have a corresponding C source folder.

If we were to make changes to System.java we would, for example, also make changes to System.c.  It is quickly clear then that we would need a mechanism for altering the remaining java classes.  Since these do not have a C file what do we then alter?  How would we rewrite a method, add one, etc.?
