------- Comment #9 from joern at huxhorn.de  2008-03-11 22:15 -------
The changes in revision 1641 won't really solve the original problem but
introduces a whole new one instead.

The following test case will always fail:
package ch.qos.logback.classic;

import junit.framework.TestCase;
import java.io.*;

public class WriteUtfTest extends TestCase {


        public void testWriteUTF() throws Exception
        {
                StringBuffer buffer=new StringBuffer();
                for(int i=0;i<100000;i++)
                {
                        buffer.append("X");
                }
                String string=buffer.toString();

                ByteArrayOutputStream bos=new ByteArrayOutputStream();
                ObjectOutputStream oos=new ObjectOutputStream(bos);

                oos.writeUTF(string);
                oos.close();
                ByteArrayInputStream bis=new
ByteArrayInputStream(bos.toByteArray());
                ObjectInputStream ois=new ObjectInputStream(bis);
                String read=ois.readUTF();
                ois.close();
                assertEquals(string,read);
        }
}

It will always produce the following exception because the String is too long
for writeUTF:
java.io.UTFDataFormatException
        at
java.io.ObjectOutputStream$BlockDataOutputStream.writeUTF(ObjectOutputStream.java:2125)
        at
java.io.ObjectOutputStream$BlockDataOutputStream.writeUTF(ObjectOutputStream.java:1968)
        at java.io.ObjectOutputStream.writeUTF(ObjectOutputStream.java:841)
        at
ch.qos.logback.classic.WriteUtfTest.testWriteUTF(WriteUtfTest.java:21)


Don't worry, I stumbled over this problem in some other project, too.
