The java.net.URL.InetAddress.getHostName() method returns simple host name
instead of fully qualified domain name on Solaris systems with NIS enabled.

Here is the JavaDoc comment for this method:

    /**
     * Returns the fully qualified host name for this address.
     * If the host is equal to null, then this address refers to any
     * of the local machine's available network addresses.
     *
     * @return the fully qualified host name for this address.
     * @since JDK1.0
     */
     public String getHostName()


Here is the test demonstrating the bug:

-------------------- Test.java -------------------
import java.net.*;


public class test
{
  public static void main(String args[])
  {
     InetAddress sin = null;

     try {
       sin = InetAddress.getByName("192.168.205.52");
     } catch(Exception e)
     {
        System.out.println("Failed. Unexpected exception :" + e);
System.exit(-1);
     }

     System.out.println("HostName = " + sin.getHostName());

  }
}

--------------------------------------------------

Output from the test on NIS-enabled Solaris:
------------------
HostName = ganimed
------------------

Output from the test on non-NIS Solaris

-------------------------------
HostName = ganimed.sparc.spb.su
-------------------------------
