[Newtest][TEST_BUG] New stress test for changing the coarseness level of G1 remembered set

    Details

    • Subcomponent:
      gc
    • Resolved In Build:
      b107

      Backports

        Description

        Remembered Set is one of the key constructs of G1, it keeps knowledge about cross region references.

        Idea of a test checking that Remembered Set works good when growing up and down:

        int[] crossRefs = {0, 100, 10, 200, 50, 300, 0};
        for (int refN: crossRefs) {
            for (x: G1Regs) {
                for (y: G1Regs) {
                    // set refN references from region X to region Y
                    WB.concMarkCycle();
                }
            }
        }
