This is simple information from Java, and reflects how java memory
allocation works.

The 27.3 GB for the entire bar is the absolute max size of the java heap
(-Xmx setting).  The 24.77 GB gray section is the current maximum size
of the heap - this is the amount of memory allocated from the operating
system for the heap.  The 16.5 GB dark gray section is the amount of
heap memory currently in use by the java program.  This number also
includes all garbage accumulated by the program that hasn't been
collected yet.
