http://cr.openjdk.java.net/~iklam/jdk12/8206115_compute_offsets_macro.v01/
As I noted in the comments on this RFE, we already have a bug where
java_lang_Integer_IntegerCache was missing from
MetaspaceShared::serialize_well_known_classes.
To avoid such problems in the future, I added a new macro in
javaClasses.hpp,
BASIC_JAVA_CLASSES_DO, which is used by JavaClasses::compute_offsets and
JavaClasses::serialize_offsets.
For clean up, I also renamed all the <Class>::serialize() functions to
<Class>::serialize_offsets() to reflect what these functions really do.
The old MetaspaceShared::serialize_well_known_classes function is now
JavaClasses::serialize_offsets.
Testing with hs tiers 1/2.
Thanks
