Actually, Java is supposed to have bitwise compatibility accross platforms (unlike
C). I know they (Sun) had severe performance problems in the early days
implementing Sun's floating point model under the Intel architecture, and that
changes were made to the VM as a result. Is this one of the consequences of these
changes? Are there ways to ensure bitwise compatibility?
