Name	Type	Description	Default Value	Your Value
ShrinkHeapInSteps	boolean	When disabled, informs the GC to shrink the java heap directly to the target size at the next full GC rather than requiring smaller steps during multiple full GCs.	true	false
Analysis	OK

Name	Type	Description	Default Value	Your Value
MaxHeapFreeRatio	int	The maximum percentage of heap free after GC to avoid shrinking. For most GCs this applies to the old generation. In G1 and ParallelGC it applies to the whole heap.	70 in range(0, 100)	2
Analysis	OK

Name	Type	Description	Default Value	Your Value
MinHeapFreeRatio	int	The minimum percentage of heap free after GC to avoid expansion. For most GCs this applies to the old generation. In G1 and ParallelGC it applies to the whole heap.	40 in range(0, 100)	1
Analysis	OK
