A DESCRIPTION OF THE REQUEST :

"java.net.NoRouteToHostException: No route to host"
in case of network problem.
This generic error message does not give any indication of which host can not be reached.

JUSTIFICATION :
For more complex network typologies, it would be incredibly useful to know /which/ host can not be reached, but including the desired host name in the exception message.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
java.net.NoRouteToHostException: No route to host "www.example.com"
ACTUAL -
java.net.NoRouteToHostException: No route to host
