A DESCRIPTION OF THE PROBLEM :
If you invoke InetAddress.getByName() with a bogus name, the error message
in the UnknownHostException is repetitive. It contains the bogus name twice.
Instead it should contain the error message, then the bogus name.

E.g. InetAddress.getByName("foobar") gives this:

   java.net.UnknownHostException: foobar: foobar

Instead it should give e.g. this:

    java.net.UnknownHostException: foobar: host not found

or somesuch.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the test program below.


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Exception in thread "main" java.net.UnknownHostException: foobar: Host not found
        at java.net.InetAddress.getAllByName0(InetAddress.java:1011)
        at java.net.InetAddress.getAllByName0(InetAddress.java:981)
        at java.net.InetAddress.getAllByName(InetAddress.java:975)
        at java.net.InetAddress.getByName(InetAddress.java:889)
        at xx.main(xx.java:4)

ACTUAL -
Exception in thread "main" java.net.UnknownHostException: foobar: foobar
        at java.net.InetAddress.getAllByName0(InetAddress.java:1011)
        at java.net.InetAddress.getAllByName0(InetAddress.java:981)
        at java.net.InetAddress.getAllByName(InetAddress.java:975)
        at java.net.InetAddress.getByName(InetAddress.java:889)
        at xx.main(xx.java:4)


REPRODUCIBILITY :
This bug can be reproduced always.
