      Description

        Since JDK 13, there is a SoftMaxHeapSize option that basically instructs GC heuristics to target that particular heap size, while leaving the headroom for allocation spikes and other contingencies. It makes sense to support this in Shenandoah.

        Backporting to 11u and 8u under ShenandoahSoftMaxHeapSize might be considered.
