These date from the first JVMs (more than 10 years ago), when memory was
expensive, and garbage collection pause time was a function of the size
of the heap, rather than the number of live objects.  In those days, it
made sense to try to have your application run with as small a memory
footprint as possible.  There are still some systems where memory is
quite limited (e.g., cell phones), but with real servers, it's more
efficient to set them to the same value.
