Javadoc states for java.net.InetAddress.getByAddress(String host, byte[] addr):

    For host specified in literal IPv6 address, either the form defined in RFC 2732
    or the literal IPv6 address format defined in RFC 2373 is accepted.

But getByAddress(String host, byte[] addr) does not check for the format of 'host'.
It allows to create InetAddress with "1234::2345::3456" hostname.

The following test demonstrates the bug:
--------- Test.java ----------
import java.net.*;

public class Test {

    public static void main(String args[]) {
 
         String host = "1234::2345::3456";
         byte[] addr = { 0,1,2,3, 4,5,6,7, 8,9,10,11, 12,13,14,15};
        
         try {
            InetAddress testAddr = InetAddress.getByAddress(host, addr);
            System.out.println("Test failed with: " + host);
            System.out.println("Created: " + testAddr);
         } catch( UnknownHostException e ) {
            System.out.println("Test passed");
         }
    }

}
-----------------------------------------
output from the test:

#> java Test
Test failed with: 1234::2345::3456
Created: 1234::2345::3456/1:203:405:607:809:a0b:c0d:e0f

I see two possible ways this bug may be fixed:
   - getByAddress(host, addr) will check the format of 'host'
   - assertion about acceptable hosts will be removed from spec
