BufferUnderflowException in ObjectSerializationInputStream

Andrew Vokhmin's report:

MINA 1.0 provides an own object serialization streams. But I have a problem
with it...
or may be It's my unawareness.

Try MINA 1.0.0 and MINA 1.0.1;
JDK 1.5.0_09
Windows 2003 Server

Source:

import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;

import junit.framework.TestCase;

import
org.apache.mina.filter.codec.serialization.ObjectSerializationInputStream;
import
org.apache.mina.filter.codec.serialization.ObjectSerializationOutputStream;

public class ObjectSerializationStreamsTest extends TestCase {

public ObjectSerializationStreamsTest(String arg0)

{ super(arg0); }

public static void main(String[] args)

{ junit.textui.TestRunner.run(ObjectSerializationStreamsTest.class); }

protected void setUp() throws Exception

{ super.setUp(); }

protected void tearDown() throws Exception

{ super.tearDown(); }

/*

• Standart Object streams works - OK...
  */
  public void testObjectStandartStreams() throws Exception { ObjectInputStream osis; ObjectOutputStream osos; //Integer msgA = new Integer(12345); String msgA = "Test"; ByteArrayOutputStream baos = new ByteArrayOutputStream(); osos = new ObjectOutputStream(baos); osos.writeObject(msgA); osos.flush(); byte xbA[] = baos.toByteArray(); osis = new ObjectInputStream(new ByteArrayInputStream(xbA)); osos.writeObject(msgA); Object msg = osis.readObject(); assertEquals(msgA, msg); osos.close(); osis.close(); }

/*

  public void testObjectSerializationStreams() throws Exception { ObjectSerializationInputStream osis; ObjectSerializationOutputStream osos; //Integer msgA = new Integer(12345); String msgA = new String("Test"); ByteArrayOutputStream baos = new ByteArrayOutputStream(); osos = new ObjectSerializationOutputStream(baos); osos.writeObject(msgA); osos.flush(); byte xbA[] = baos.toByteArray(); osis = new ObjectSerializationInputStream(new ByteArrayInputStream(xbA)); osos.writeObject(msgA); Object msg = osis.readObject(); assertEquals(msgA, msg); osos.close(); osis.close(); }
