Is this indicative of a memory leak in Java?

Does the following graph indicate that I am using memory and it is not being garbage collected?

enter image description here

I expected the orange graph (the allocated heap) to go down once I start using less of the heap.

It is clear from the graph that your JVM is capable of shrinking the heap. This can be seen from the orange line taking a slight dip just before 3:10pm.

However, later on the JVM chooses to not shrink the heap. This is almost certainly because an insufficiently large fraction of the heap is unused. The behaviour is controlled by -XX:MinHeapFreeRatio and -XX:MaxHeapFreeRatio.
