JDK-8017163 - G1: Refactor remembered sets
Description
To help analyze the trade offs in the G1 remembered sets, it would be beneficial to log the size of the different kind of data structures used in OtherRegionsTable.
Comments
Adding first draft for this enhancement. It was observed that reordering the declarations of the added methods in heapRegionRemSet.hpp has a rather significant performance impact when the added JFR event is turned off.
