Assignee: Paulex Yang
> Stream-based replacement does not work in ObjectOutputStream
> ------------------------------------------------------------
>
> Key: HARMONY-1429
> URL: http://issues.apache.org/jira/browse/HARMONY-1429
> Project: Harmony
> Issue Type: Bug
> Components: Classlib
> Environment: Win XP
> Reporter: Mikhail Markov
> Assigned To: Paulex Yang
> Priority: Critical
> Attachments: ObjectOutputStream.patch, ObjectOutputStreamTest.patch

> Patch for JIRA HARMONY-851 broke stream-based replacement mechanism in ObjectOutputStream.
This brokes normal RMI work as it uses this mechanism.
> For example, the following test fails on Harmony and pass on RI:
> import java.io.ByteArrayOutputStream;
> import java.io.IOException;
> import java.io.NotSerializableException;
> import java.io.ObjectOutputStream;
> import java.io.OutputStream;
> ============== Test.java =================
> public class Test {
> public static void main(String[] args) throws Exception {
> try {
> ObjectOutputStream out = new TestObjectOutputStream(new ByteArrayOutputStream());
> out.writeObject(new NotSerializable());
> } catch (NotSerializableException e) {
> }
> }
> private static class TestObjectOutputStream extends ObjectOutputStream {
> public TestObjectOutputStream(OutputStream out) throws IOException {
> super(out);
> enableReplaceObject(true);
> }
> protected Object replaceObject(Object obj) throws IOException {
> if (obj instanceof NotSerializable) {
> System.out.println("replaceObject called: obj = " + obj);
> }
> return obj;
> }
> }
> private static class NotSerializable {
> }
> }
> ======================================
> Output on RI:
> replaceObject called: obj = Test$NotSerializable@1b3d3e
> Output on Harmony is empty (replaceObject is not called).
