Rana Dasgupta commented on HARMONY-4477:
----------------------------------------

Thanks Chunrong.
1) Also seems that there is a potential to avoid a lot of data structure duplication here by using pre/post processing GC<->VM hooks that Xiaofeng discussed on the list.
2) About force_major_collect...I agree. To use this limited test to check the CU machinery it is OK to turn the option on, I think. But in our design, we commit to do CU at every major collection only...not at every collection.

This is ready for commit IMHO. We can add the stuff in 3997 ( lazy exception handling impact ) later after this core functionality goes thru some testing.
