De-Serialization Bug - Class Vector

Hello,

I have been figthing with a De-serialization problem in TINI, and it looks
more and more like a bug:

Find the code enclosed below:

The issue is: serializeTest will always serialize the Vector in
serializeTest: I have tested up to 120 elements.

However, De-serialization works only up to 40 elements , but fails at e.g.
50 with the following error:

Starting de-serializing         // Printout from my code

java.lang.ClassCastException
   in java.lang.reflect.Array.set(@JPC=15022d)
   in java.io.ObjectInputStream.???
   in java.io.ObjectInputStream.decodeTag(@JPC=160075)
   in java.io.ObjectInputStream.readObject0(@JPC=290029)
   in java.io.ObjectStreamClass.readObjectStreamField@JPC=1a015d)
   in java.io.ObjectInputStream.defaultReadObject(@JPC=170023)

   in java.io.ObjectInputStream.decodeTag(@JPC=16006d)
   in java.io.ObjectInputStream.readObject0(@JPC=290029)

   in no.oss.rpc.simple.test.TestRPCReceiver.initialize(@JPC=11004e)
   in no.oss.rpc.simple.test.TestRPCReceiver.<init>(@JPC=4)
   in no.oss.rpc.simple.test.TestRPCAsServer.test(@JPC=a0004)
   in java.lang.System.???



I thought it had something to do with the amount of data stored in the
Vector, so for 50 elements I changed addresses.addElement("Slituveien");
into addresses.addElement("S"); but I get the same exception.

This surely seems to be a bug or undocumented limitation. Any workaround?


Please Help !

----------------- Code ---------------------------


Vector addresses = new Vector();
System.out.println("Vector capacity: " + addresses.capacity());

public voide serializeTest() {

for (int i = 0; i < 50; i++) {
        //addresses.addElement("Slituveien");
        addresses.addElement("S");
}

//TINIOS.setStackSize(5000);
try {
        System.out.println("Starting serializing");
        byte[] serializedVector = serializeObject(addresses);
        System.gc();
        Thread.sleep(1000);
        System.out.println("Starting de-serializing");
        Vector vector = (Vector)getSerializedObject(serializedVector);
        System.out.println("Deserialized: " + vector);
} catch (Exception e) {
        e.printStackTrace();
} finally {
        System.exit(0);
}

}


public static Object getSerializedObject(byte[] serializedData) throws
IOException, ClassNotFoundException {

        ByteArrayInputStream byteInputStream = new
ByteArrayInputStream(serializedData, 0, serializedData.length);
        ObjectInputStream objectInputStream = new
ObjectInputStream(byteInputStream);

        return objectInputStream.readObject();
}


public static byte[] serializeObject(Object object) throws IOException {

        ByteArrayOutputStream byteOutputStream = new ByteArrayOutputStream(200);
        ObjectOutputStream objectOutputStream = new
ObjectOutputStream(byteOutputStream);
        objectOutputStream.writeObject(object);

return byteOutputStream.toByteArray();
}
