/*
 * Design Note:
 *
 *      o   Chose to include lineNumber etc stuff in message by default because in apps where this is not desired -
 *          (fancy gui apps) they are more likely to be the ones to override the exception mapping to message anyhow,
 *          and tune it themselves. Its the simple apps that do little but dump the string representations of a
 *          message that are more likely to want to know the line number (a bit of a guess).
