#5 improve error handling and display
Refactor the error handling and exception display - it would be great if there would be an option controlling how error messages are displayed. maybe one style for machine-readable error descriptions and one for bipedal carbon-based life forms. maybe another option for the verbosity of it - full exception with stacktrace vs. short error description.
example using the http bridge:
./get_mbean_proxy -H bobweb15 -p 4711 -m java.lang:type=Runtime/Uptime -o NAGIOS -v
get_mbean_proxy CRITICAL - 500 Internal Server Error
Verbose output
