RFR: 8370079: Re-enable vmTestbase/gc/vector/CircularListLow and LinearListLow with SerialGC

Fri Oct 17 12:21:16 UTC 2025

Trivial re-enabling these two tests with SerialGC. I am leaving [JDK-8368191](https://bugs.openjdk.org/browse/JDK-8368191) open for now and plan to close it after monitoring CI for a while.

Test: 2K runs of the previously failing tests
