G1 adds old gen region rs lengths to _young_rs_length

    XMLWordPrintable

Details

    • gc

    Description

      The max_rs_length value and related predictor are used to predict total young gen remembered set length.

      During the Free CSet phase we add not only young gen regions to the local total that is later assigned to max_rs_length, but also old gen region remembered set sizes.

      Fortunately G1 does not (correctly) use this resulting value to update predictions. It is just wasted effort.

      Fix this.
