#12256 Improve JVM Arch Detection 

Notify the user if the JVM architecture could not be detected, instead of silently defaulting to 32-bit. Also add a max heap parameter. On machines with RAM sizes in the order of 64GB plus, the initial heap could be multi-gigabyte. This can lead to an out of memory error when checking for the version.
