Why is it useful to print an error message and terminate only if the compilation mode is compressed
and the heapsize is > XXX?
Even for compilation mode = uncompressed, each OS sets limits on max addressability and so
the heapsize has different limits on different OS's.
The max heapsize that works in each mode really depends on OS and java addressability and
max memory installed on the machine. This kind of information is better in a tuning guide.
It may be OK to let the program crash if the JVM at runtime tries to access more heap than
