method in an
environment where neither a proper DNS lookup nor an /etc/hosts
entry exists for a given host, the following exception will be thrown:
java.net.UnknownHostException: <hostname>: <hostname>
at java.net.InetAddress.getLocalHost(InetAddress.java:1425)

Instead of just throwing an UnknownHostException and giving up, this
method grabs a suitable hostname from the exception and prevents the
exception from being thrown. If a suitable hostname cannot be acquired
from the exception, only then is the UnknownHostException thrown.UnknownHostException
- is thrown if hostname could not be resolvedApache Camel
