Hi, Please review
When do dynamic dump, the call to LambdaForInvolkers::append_filtered for generating lambda holder classes will only allow the result which matches the filtering list to be added . This filters out the SPECIES method handle holder classes, and they won't be archived in dynamic shared archive. The patch is doing followings:
1) Removed the call to LambdaForInvolkers::append_filtered, instead just call LambdaForInvolkers::append so the SPECIES can be added to the regeneration list.
2) Added an enum for shared flag in Klass, _generated to indicate the class is regenerated and it should not be loaded from CDS if CFLH is enabled. If the class is a SPECIES and also loaded from base archive, skip regenerating it for dynamic archive.
3) Removed SystemDictionaryShared::is_hidden_lambda_proxy since it is only used in one place where checking CFLH --- moved the checking code into KlassFactory::check_shared_class_file_load_hook to make code cleaner.
Tests: tier1,tier4
Thanks
Yumin
