When starting a Sun JDK/JRE VM, the bootstrap executable will set initial
and maximum heap numbers (analogous the -ms and -mx flags).
Specify the preferred numbers for your app below. The units are in megabytes
(MB). Note:
The initial heap must be less than, or equal to,
the maximum heap.
The initial heap cannot exceed 32 MB.
The maximum heap cannot exceed 512 MB, nor be less than 4 MB.
