      Description

        The Shenandoah implementation has been improved to allow arbitrarily low initial heap size. Before this change, Shenandoah needed at least 10 regions to cover `-Xms`. With large heaps and/or larger regions, those 10 regions could use a significant amount of space. This requirement is relaxed now, and Shenandoah can run with the lowest `-Xms` that the shared JVM code can accept.
