Many of the fields in archived java.lang.Class objects have predictable values that can be assigned during archive creation time. We should explore doing this after JDK-8315737.

For visualization:

Try "java -Xshare:dump -Xlog:cds+map=debug,cds+map+oops=trace:file=cds.map:none:filesize=0"

See this cds.map:
