Checks basic properties of bitmap memory cache producer operation, that is: - it delegates to the
{@link MemoryCache#get(Object)}. - if get is successful, then returned reference is closed. - if
{@link MemoryCache#get(Object)} is unsuccessful, then it passes the request to the next producer
in the sequence. - responses from the next producer are passed directly to the consumer. -
listener methods are called as expected.
