| Level 1 Cache using Soft referenced objects in a Map.
If map entry value object is not actively being used, i.e. no other
object has a strong reference to it, it may become garbage collected at
the discretion of the garbage collector (typically if the VM is low on
memory). If this happens, the entry in the SoftValueMap
corresponding to the value object will also be removed.
