The Heap Contents pie chart gives a graphic overview of the distribution of objects on the heap. The color coding helps you determine how much of the heap that consists of large, small, and pinned object chunks as well as how much memory is considered dark and how much is free. The amount of dark matter indicates how much space on the Java heap that is wasted due to fragmentation. It is normal to have a certain amount of dark matter on the heap.
For information on how to minimize dark matter, see Minimize Dark Matter in the BEA JRockit Diagnostics Guide.
The table below the pie chart (Figure 10-2) lists all objects with the exact data: memory in MB and percentage that they occupy of the heap.
