java.nio.channels.DatagramChannel.send(ByteBuffer src, SocketAddress target)
throws unexpected SocketException on solaris.

Here is the example:

-------test.java---------

import java.io.*;
import java.net.*;
import java.nio.*;
import java.nio.channels.*;

public class test {
    static InetSocketAddress getFreeISA() throws IOException {
        ServerSocket soc = new ServerSocket(0);
        int port = soc.getLocalPort();
        soc.close();
        return new InetSocketAddress(InetAddress.getLocalHost(), port);
    }

    public static void main(String [] args) {
        try {
            InetSocketAddress sender = getFreeISA();
            DatagramChannel sndChannel = DatagramChannel.open();
            sndChannel.socket().bind(sender);

            InetSocketAddress receiver = getFreeISA();
            DatagramChannel rcvChannel = DatagramChannel.open();
            rcvChannel.socket().bind(receiver);
            rcvChannel.connect(sender);

            sndChannel.connect(receiver);

            sndChannel.send(ByteBuffer.allocate(10), receiver);

        } catch (IOException e) {
            e.printStackTrace(System.out);
            return;
        }
        System.out.println("OKAY");
    }
}

Note, also JCK1.5-runtime api/java_nio/channels/DatagramChannel/index.html#Generated
fails as a result of this bug:

Name: mmR10223 Date: 08/28/2003


Filed By : J2SE-SQA [###@###.###
JDK : JDK1.5.0-b15 (b02)
JCK : JCK1.5-runtime
Platform[s] : Solaris (sparc, x86)
switch/Mode : default
JCK test owner : http://javaweb.eng/jck/usr/owners.jto
Falling test[s]:
        api/java_nio/channels/DatagramChannel/index.html#Generated [DatagramChannel0034, DatagramChannel0035, DatagramChannel0036, DatagramChannel0037, DatagramChannel0042, DatagramChannel0043, DatagramChannel0044, DatagramChannel0045, DatagramChannel0050, DatagramChannel0051, DatagramChannel0052, DatagramChannel0053, DatagramChannel0058, DatagramChannel0059, DatagramChannel0060, DatagramChannel0061]

This is a new test which is absent in previous JCK. It fails using all JDK1.5.0,
JDK1.4.2 builds on Solaris (sparc, x86) platforms only, but it passes on other platforms.
The test hangs if it is run using script which is shown below.


Test source location:
=====================
/java/re/jck/1.5/promoted/latest/binaries/JCK-runtime-5/tests/api/java_nio/channels/DatagramChannel/GeneratedTests.java

jtr file location:
==================

How to reproduce:
=================
Run the following script (you may need to change its variables)
 
--- script start ---
#!/bin/bash

JCK="/java/re/jck/1.5/promoted/latest/binaries/JCK-runtime-15"
JDK="/java/re/jdk/1.5.0/promoted/latest/binaries/solaris-sparc"
CLASSPATH="$JCK/classes:$JCK/lib/javatest.jar"
 
$JDK/bin/java $switches -cp $CLASSPATH javasoft.sqe.tests.api.java.nio.channels.DatagramChannel.GeneratedTests -network.tcpPortRange 0
--- script end ---

Script output:
============
Test hangs
