InitiatingHeapOccupancyPercent int The percent occupancy (IHOP) of the current old generation
capacity above which a concurrent mark cycle will be initiated
Its value may change over time if adaptive IHOP is enabled,

In the latter case a value of 0 will result as frequent as
possible concurrent marking cycles. A value of 100 disables
concurrent marking.
Fragmentation waste in the old generation is not considered
free space in this calculation. (G1 collector only)
