‘-XX:MinRAMPercentage’ JVM argument will be used to compute Java heap size only if your overall available memory’s size in the physical server (or in the container) is less than 250MB
By default, the virtual machine grows or shrinks the heap at each collection to try to keep the proportion of free space to live objects at each collection within a specific range. This target range is set as a percentage by the parameters -XX:MinHeapFreeRatio= and -XX:MaxHeapFreeRatio=, and the total size is bounded below by -Xms and above by -Xmx .
