memory-usage

I have a java application that uses a lot of memory when used, but when the program is not being used, the memory usage doesnt go down.

Is there a way to force Java to release this memory? Because this memory is not needed at that time, I can understand to reserve a small amount of memory, but Java just reserves all the memory it ever uses. It also reuses this memory later but there must be a way to force Java to release it when its not needed.

System.gc is not working.
