      Description

        There is some confusion what -Xms really means. Current code assumes it only means "initial" heap size, which allows it to uncommit the heap below -Xms. However, users expect -Xms to mean "minimum heap size" to set the low watermark for heap shrinkage. We need to amend Shenandoah to avoid uncommitting below that watermark.
